While I gave this 4 stars similar to the previous book, I actually enjoyed this one much less. Overall, I think it's still worth 4 stars compared to other books I've only rated with 3, but my personal enjoyment definitely dipped here.
The elements that I don't care much about, 1) the overwhelming detail given to crafting magic items (even when they aren't that relevant), and 2) the harem, ended up occupying significantly more page time than the actual plot this time around. Those elements have always been present, but I was mostly here for the story.
I like some detail to theory crafting magic and spells and such. A good example would be the Divine Dungeon series by Dakota Krout. Unfortunately, I don't give two shits about replicating modern technology in a medieval fantasy land. I don't like the idea of introducing mortars and firearms. Not to mention, I got annoyed with how often Daniel held down the trigger and 'walked' his fire across the enemy. That's something I would picture more with a faster rate of fire, not with a pistol that only fires one round per second. You don't really walk your fire with a normal semi-auto pistol and you can empty a magazine in about 3 seconds.
I kind of lost touch of the idea that the main character was very competent other than in special circumstances. He constantly acted like he was a one man savior squad and had a million things to do all the time, but to me he just seemed like a typical programmer type that had poor time management skills.
The characters really flattened out this book as well. Avilla is the easy example as she basically turned into an Easy Bake oven for the duration of this story.
Overall, not a bad experience, but I think I'm leaving this series here. The author seems to be writing other series now and isn't consistently releasing on this one which is rarely a good sign.
