Behold, the first actual boss in my roommates game (as apposed to minibosses), Shiitaking (obviously a portmanteau of shiitake and king). I don't know how much I can say about the game, but there will be a LOT of different elements that can be infused with your weapon, and, along with basic weaknesses, I've been considering bonus weaknesses shown via shinier aspects of the character. For example, this guy is weak to ice (If I remember the element relations), but see his shiny leaves? Use some fire to burn them off and reduce his deffences.

Also yes, thats his belly button, get your ming out of the gutter (You know who you are).
