The Affinity Collector: A Fantasy Isekai LitRPG Series

Rate this book
Two deaths, and one life that has an incredible advantage.

At only 8 years old, Weldin had just had his dual Affinities bestowed upon him by the Goddess Athera when he ended up in a Nexus Rift far exceeding his Level. To make it worse, the Affinities he ended up with, Light and Energy, weren’t exactly the best when it came to offensive capability, and he struggled to kill any of the higher-Level monsters that stood in between him and his freedom. The lack of a powerful Ability to defend himself, as well as a lack of worldly knowledge, eventually led to his downfall.

But that wasn’t technically the end of Weldin’s existence, as just as his mortal form succumbed to its fatal wounds and his soul slipped away, a soul from another world was slotted into the empty shell to take over his abandoned body. This new soul was from Earth, and with it came a plethora of knowledge that could take advantage of his Affinities, in ways that his current world had never seen before. Even more than possessing otherworldly knowledge, the introduction of a new soul into Weldin’s body had seemed to initiate some other capabilities, such as the unique ability to unlock additional Affinities.

Now, all he has to do is clear a Nexus Rift where everything can easily kill him if he makes a mistake, navigate a world where those in power want to possess him because of his unique Affinities, and somehow survive an Academy full of 8-year-olds who have just learned that they have incredible magical powers – all so he can progress his personal quest to collect all of the Affinities he can.

This story contains LitRPG progression mechanics and stats, as well as isekai/portal fantasy elements. Contains no sexual content or harems.

Another great beginning by Jonathan Brooks.

Immediately went to check if a book 2 was available and unfortunately, we're looking at late April for it.

Nonetheless, a really fun read.

Didn't add up

Couldn't finish. There were too many tropes that kept me from enjoying the book. The first trope is dues ex. There is nothing worse than the authors hand weighing on the scale without a believable scenario. The next trope is the MC or some advisor hiding information back that would solve many of the misunderstanding or conflict.

All that being said, what made me stop was that the timing of the cycle never added up to how reality was explained. First, how is he 8. You have to be 8 to get your affinities. His mother died in a monster wave that occurs the year after the affinity ceremony. That means he had to be born during the year of the ceremony the previous cycle and his mother died the next year. The story says the went to other cities during other monster waves so it doesn't add up. Also, it would suck to born the year after the ceremony because you would 17 when you got your affinity. The people that found the MC talk about how the academy would be.gearing up for next years intake but the academy intake would only happen every 8 years based on the ceremony. There would be no planned intake the year after the MC left the rift (a year after the last ceremony).

This a steaming pile of dog feces. The reviews are horribly fake, even on goodreads. The MC is an 8 year old boy who acts like a well adjusted but ignorant adult. The author tells us far too much showing little to nothing and forces a completely unbelievable series of events that I can't even read more than a chapter or two. The editing is a computer as no human editor would let this much bad writing past.

The book needs editing to remove the constant rehashings of events.

The plot is okay but nothing special. After the early events i found the stay at the academy very dull. Unfortunately, the protagonist seems to be way more enthusiastic about his skills than i was.

My biggest problem with the book was the lacking motivation. As in cultivation stories the protagonist does all only to become stronger and has no meaningful relationships or a real personality..

Great book until the end.

Many of the decisions Jeremy made on what to hide and what to reveal make no sense. And this is coming from someone who used to be an intelligence analyst in the army, as well as a short stint with other Agencies.

Minor Spoilers below but I did my best to obfuscate.

It feels like the author had the ending and the second book already laid out and wanted to ham fist reasons for it. The conflict with one of the professors could have been entirely avoided if he just explained some things.

And this is ignoring the idea that hundreds of years old, and even thousands of years old being who have made the study of light their life’s work. Especially considering that it was discovered in OUR world by a decades year old guy with a prism and a thermometer. But I can suspend that disbelief for the story.

What I can’t suspend is the organization behind the second instructor, wanting to capture someone that something weird happened to is not enough of a reason to get organizations like that to move feet. Now if Jeremy HAD explained things like the Laser, THAT would get their attention, AND it would have made the ending actually make more sense.

It really feels like Jeremy is acting like someone who spent over 20 years Cold War era spy jumping at everything, than a zero life experience, disease ridden man with the memories of a village 8 year old in from the middle of nowhere.

Wordy and somewhat clumsily written

Way too much exposition between the moments of action. Also, the writing was a bit clumsy in places, particularly with numbers-- '1' instead of 'one' -- that sort of thing. I also found it difficult to picture the protagonist as a child. I know that mentally the MC is supposed to be a teen, but still, it felt more like an adult pretending to be a kid.

Like the other books by this author, it satisfies the want for abilities to combine and to do powerful things.

Unfortunately, this also applies to the rather unsettling amount of information that every other character *demands* from the MC. Everything the MC does is impossible and therefore the other characters are excused from invasive questioning and record keeping.

The legitimate answer to all of these questions should really be, "I don't know, I am 8 years old"

While I enjoyed the read and will most likely pick up any sequels when they come out, this book was a bit frustrating to me. There's not a lot of world building, character development going on. Reincarnator goes straight from dungeon scenario to school scenario, and those are closed off environments. So absolutely no exploring the world or explaining how things work and what's really going on ( which probably makes the book easier to write ). I mean, the kid was at school for 3 years and didn't get any more information about things when he had access to other students, teachers and a huge library?

Octaeteris Cycle 1: The Affinity Collector

Weldin had just completed his blessings ceremony when things took a dramatic turn. The portal he went through didn’t take him to an academy to learn about his blessings, but a rift portal where every creature in there could easily kill him. In fact, not long after he arrived, they did just that. As his soul left his body, a soul from Earth filled and took over his body. Fortunately, Jeremy has Weldin’s memories and twenty some years of knowledge from Earth. Unfortunately, he is stuck in the same rift that just killed Weldin.

This Isekai litrpg was a great read! Weldin does a good job trying to escape this rift that he has no right being in, but Jeremy is able to apply scientific knowledge to take it up to the next level. I did really enjoy the academy aspect of the story and hope to see more of his classmates in the next book! Miles Meili does a great job with the narration!

This is a fairly fun book, with a number of flaws that mostly don't detract too much from the story.

This is a fairly standard LitRPG setting, where the world is full of dungeons, er "rifts" in this case, that spew forth monsters every 8 years. Training specialist fighters and wizards to combat these monsters is thus a priority. Since it's a LitRPG, there's a game-like progression system governing advancement that accepts as normal.

Everyone gets 2 magical affinities at age 8, and gets trained in mass academies until about age 16. This leads to the first irritating flaw, many of the characters are aged 8-10, but talk and think like adults. Real kids that age don't think very clearly, and aren't very rational. I remember pretty well the foolish things I got up to at that age. I ended up willfully ignoring this, because I'd rather read about interesting, intelligent characters than realistically written pre-teens.

Weldin gets accidentally transported to a dungeon at age 8, instead of being teleported to an academy as intended. He does OK for a short while, but then gets killed by the monsters.

Enter the Isekai element. Jeremy, who is from Earth, dies at 16 and takes over Weldin's recently deceased body. Because Jeremy's fairly well read, he figures out how to make lasers using Weldin's [Light] and [Energy] abilities, and eventually clears the dungeon.

This is the second sticking point, the damage the lasers do isn't really plausible, because the energy levels aren't high enough. Again something I had to willfully ignore.

When he does re-enter civilized society, Jeremy keeps his off-world origin and laser-making abilities secret, for no good reason that I can discern. This is something of a habit for Brooks, having his protagonists tell unnecessary lies because they're paranoid. It's painful on occasion because the lies aren't all that believable, and Jeremy doesn't get nearly enough pushback for telling fairly obvious falsehoods.

There are further misadventures, and some time spent on school, though not really at length or in detail. Eventually it turns out there are nefarious forces, and Jeremy's lies about his origins and abilities are retroactively justified, though personally I think he'd have done better overall if he'd been honest.

The book ends rather abruptly midway through Jeremy's 3rd year at school, when he's still 10. This is very much first in a probably very long series, rather than a complete novel.

Overall I had fun reading it. Most of the fun came from reading about Jeremy pushing the magic system in directions that have never occurred to any of the locals.

A good Isekai transported to another world in a different body story. 8 year old gets his two affinities and is supposed to be transported to school to learn how to use them when someone blows up the group he is with. He is sent through the portal but because of the energy, he is sent somewhere else. He is sent to a Nexus portal, one way above his level all alone. He does pretty well figuring out how to survive for a little while before one of the monsters does kill him. That is where Jeremy comes in. He was a young man on earth dying in hospice when he wakes up in the body of this 8 year old. He spent the last few years of his life watching videos, listening to audiobooks and reading so while he isn't an expert on anything, he does have a broad base of knowledge. He uses this knowledge to get the most out of his affinities.

He ends up being an impossibility in this world, because after he defeats the portal, he gets a third affinity.

fun

An 8 year old gets his System access and is on his way to the Academy to learn. Tragedy strikes and he is trapped in a Rift (dungeon). He dies. A 16 year old in another world dies and is reincarnated into the body of the 8 year old. He survives the Rift and gains new abilities. He escapes and is rescued and taken to an Academy. He gets thrust into yet another Rift and survives before finally arriving at the Academy. There he learns about the world including finding out that he is on the other side of the world from where his body started. Three years later he goes to a “safe” Rift and his world is upended again. He now starts a plan to forge his own path and ensure his freedom. Book ends

Good YA story. Great pacing. Interesting world and system. Nice progression. Great setup for the arc. Please enjoy

Can't give it more than 3 stars:
1. So, the teacher tells the kids that they may reach the next threshold (weak 1) of one of their affinities "while learning in the Academy" - i.e. over the next 8 years.
And yet, the MC increases one of his affinities from the same starting level as the other kits to weak 1 in just 6 months simply doing the exercises that the instructors gave him. HOW did that happen? No explanation in the book!
2. First the MC tells the dean that he was able to finish his first rift because of some unknown person that cleared it. But few days later, when the same dean betrayed his privacy and shared his info with 2 other instructors, the MC decides that somehow it is OK to tell them how he cleared alone the level 30 rift while still level 1? Why change the story?

Amazing new book!

Wow! What a great story! I read it all in one long session.

It’s an entirely new kind of world but it’s not a typical transmigration story at all, although the MC has been transmigrated. The MC is not super powered. He has only the normal powers of the newly awakened boy who’s body he now inhabits.

He is able to learn to use his new abilities through trial, error and desperate need. Then he finds ways to use his Earth knowledge to adapt his magic abilities in new ways. That begins his adventures - but he is just 8 years old, weak and vulnerable.

I can’t wait for the next book!

Great story, but the premise was questionable

I loved the story of how Jeremy thrived in his isekai’d new life, but I had a lot of trouble suspending my disbelief that all of this was happening to Weldon when he had only just turned 8. An 8 year old is generally old enough to understand the difference between right and wrong, but there is no way that Weldin was as capable as he was. And that whole society to completely sever familial ties at 8 seems unlikely.

Jeremy was much more believable, and I rather loved the twist at the end of this book. I will be interested to see how Jeremy progresses as this series develops.

I enjoyed this one although I am not sure why. I liked the MMC although I found the internal voice didn't actually change that much even with the big change and I felt sad for the boy. I liked the innovations but was screaming LIGHT SABER a little too much and instead he went with laser cannon? It was a switch when the MMC eventually got to the Academy and a bit disappointing as we glossed over it. It had a lot of potential. I checked to see if there was a book two and saw there was a betrayal and it yucked my jam. Overall a good litrpg.

So many plotholes and inconsistencyes... Starting from the age of the MC, it's like the author has never seen an 8 year old kid. And the list goes on and on. I am tempted to say that most of these are things that any normal person would notice, but not an AI... (Edit: Nvm the last bit, noticed that I had read his earlier Dungeon World series and it had very similar problems while written before AI... So maybe it is just the fast pace he is writing these... 3 months for a book doesn't leave much room for planning or editing.)

Gotta Collect them All

This was an interesting story about a boy who got lost on his way to school, and something happened and his body got a new conscience from Earth, and this guy know a lot that helped him get along in this new world. A lot has happened to him including getting more affinities, and he made friends. I am on pins and needles on what is going to happen next. It has become a real page turner.

Unexpected fun

This was a fun read. The MC is confident due to his knowledge but still inexperienced due to even his prior life being young and bedridden. I would like a more fleshed out world and power system for the next book since I feel like I don’t know the scale that abilities can have. What level of destruction can high levels do? All we know is the dragon but that was vague. Can they destroy cities? Continents? Or just city blocks? Can’t wait for more

Unlike most other litrpg series

I find only two things disturbing about this story...

The first thing is why , after six months of living on his own, none of the physical attributes improved...

The other thing I did not enjoy about this story is the fact that it's going to be a while before the next installment.
Thoroughly enjoyed this book and was very disappointed when it ended, but thoroughly looking forward to the next installment

Here we go again

Another great book from an incredible author. This is the first book of a new series and will probably be as great a series as the author's others is this book is any indication. Interesting beginning, I won't spoil, for a book of this genre but quite fun(for the reader). All I can say is read it. If you read this author's others works. You will enjoy this book immensely. Now comes the wait for the next book.

Unique Magic System

I am a fan of LitRPG in general and I especially like unique magic systems.

This book does a great job with a new (to me anyway) magic system. The MC is not perfect but not a dufus either.

I'm already impatient for the next book in what promises to be a great series from one of my favorite authors!

I really enjoyed the idea of the book, and much of the execution was fun. I rather enjoyed the ‘theory crafting’, which I can’t say is always true.

Some issues for me:
• the author does not portray eight year olds accurately, particularly early in the book.
• side characters are barely two dimensional

Disappointed…that I have to wait

I really enjoy when I get to read about how the MC learns more about magic systems, try to exploit all loopholes and use their knowledge to figure out new possibilities. I did feel as if the novel was too short, but I’m biased. I love to just binge on these kinds of novels, so I don’t count it against the author.

Fun well written story

Thank you really enjoyed this book. The magic system is not rushed and feels organic. The MC is likeable and without complication. There is not much other character development but right now that feels ok as they don’t feel important. Few bug time skips which are the only disruptive element.
Good fun read though.

interesting and unique

While a little slow paced at times, this was a good story. World building was interesting and well defined. Some of the logic of the system is a little weird with applying skills/level ups, but I guess that helps with the power creep that so many LITRPGS struggle with.

A Must Read Series!

Jonathan Brooks hands down is one of the best LitRPG authors out there! He absolutely nailed this one with the power system, mystery, and world building! I loved the start with Weldin! It built so much sympathy, just for him to fail…or so we thought! Overall, this is a great start and I can’t wait for what’s to come with this series!

Interesting story and magic system

Well written and edited. The story is unique and well written. The world building is very interesting and well thought out. The magic system and ‘academy’ are also fantastic and interesting. Looking forward to the next book.

New series!

I thoroughly enjoyed the first book of this series, though I will say it took a little while to switch to the new personality. The system for advancement looks to be one I haven’t seen before, and I enjoyed it. Look forward to the next book in the series!
