As a quick question to this I would think the chance of it being useful is good but a encounter ender, not sure.
From my understanding, you need to hit, so none of the enemies can have cover or similar. They need to be spread out or you risk hitting confused guys with splash damage.
You need to have invested multiple feats to do multiple creatures.
Min lvl 8
Only have 1 or 2 encounters a day.
They all need to be effected by confusion.
Finally they need to roll the correct percentage numbers on their turn.
I know this is an old post but i wanted to check i was seeing this correctly before i try using it on my alchemist
