Two illaoi skin ideas/concepts
The idea that she's carrying around that spherical thing with the deity's eye, or whatever it is, inside kinda reminded me of something.
Bowling! The deity thing is replaced with a bowling ball or a bowling ball carrying case since it has a handle, and the tentacles are replaced with bowling pins. yeah I realize that replacing fluid moving tentacles with inanimate bowling pins is strange and sounds bad, but thinking of her smacking people with a bowling ball gave me a laugh. IDK how to really consider her E on it though. that one's tricky.
aaaaaaand Takoyaki Illaoi Takoyaki is basically a japanese treat that is literally a round ball of batter and seasoning with octopus bits inside. "grilled octopus" replacing the deity icon with an octopus ball and the tentacles get a redder hue rather than a greenish one since it's actual octopus, and grilled at that.
