i can confirm as someone who occasionally dabbles as a microwave mage that the max amount of clouds is NOT 15 and this is about in-game clouds…hopefully
but the other things you said were true, especially:
“Clouds are bugged and only hit once during their lifetime.”
by far the worst bug
I main Microwave Mage! Poison damage is fun, because even when the clouds don’t do that much damage, they still feel like a threat, and people tend to avoid them because of the damage that they do anyway.
I never noticed any issues, but I’d be happy to have them fixed.
