I like to think that this character (Improviser would be a nice name) has few ideas of actual good summons, so they go for random stuff like raising a stairwell or hurling a window at the opponent
I don’t know if it’d be possible (let alone easy), but YOMI Hustle map interactables would be cool (though it’d suck since most modded characters would have to be updated for it); For example, stairs that do damage if a player falls down them/is kicked down them, or a special attack that triggers when near something such as a water jug or a loose pipe
