This is a solid dungeon core book and I recommend it. The issues other people have with the music and sound effects CAN be ignored due to being relatively uncommon, maybe showing up once or twice every 4 chapters (other than the first 1/4 of the book where it is used often).
The biggest gripe I have is the pixie helper. She can be extremely annoying, insisting the dungeon mobs be named ridiculous things like Steve and Buttercup (for an undead SHADOW dungeon) and while I like giving scary things funny names this gets annoying when the pixie tries it on EVERY boss. This would be something I could ignore but it’s HOW the pixie gets away with these names… she begins crying and throwing a tantrum like a 10 year old in a toy store until the dungeon gives up and assigns the name. It irks me that this character is so annoying but DAMN does the voice actor sell it.
Good dungeon core book, would recommend.
