Every enemy in Guildrun
Guildrun fields eighteen monsters, from mushroom archers and slimes up to the hydra and the three dragons. Each one is retuned for every floor and difficulty it appears on, which is why the game carries 644 separate enemy variants.
Each enemy page lists the abilities it carries, the stat line of every variant and the encounters it turns up in, so you can see what a floor is about to throw at the guild.
