Y'know, messing with random artifacts in a dungeon is a really good way of finding yourself filling up said dungeon. This is like random dungeon magic items 101... Sketch Comm for @foxmallow.bsky.social :3
Ignus, a white brown and black kitsune in purple wizard robes. 

He's fattened up to the point of filling a whole dungeon room, as prismatic magic energy radiates around him and a magic artifact laying on his chest, swelling him up fatter and fatter.

Coach has been on his feet all day. Can’t blame him for wanting to rest his heavy ass down and rest. Glad that his seat didn’t mind helping him out. Goldie/🎨: @sizabledanger.hyper.wang #furrynsfw

i mean it gets me into fights more often to practice how to do it without as much time committment which is great for my ADHD, so i dont mind it for the time being

Drawing of Koffe resting a tray of coffee on his gut as if it were a table, it being so huge and bulging forwards that he can do it standing up. He’s also holding a cup between his pecs. The next drawing shows Salem using the goat’s ass as a counter in the same fashion, it’s unclear if Koffe actually notices
