Some dude just tried attacking my base and he used a bunch of insanity 3 potions. I was still able to play better than him even with insanity 3, but i got really annoying and when I got him low I get hit with the metric ton of blue and black fire or gas or whatever in my face which he used to run away. He left the game after getting away though so I guess he was just trying to get rid of the combat tag so he could escape.
So yeah I’d say insanity potions can be useful, provided the person you’re using them on doesn’t either already have insanity or warding. You also have to not suck too.
