Even with boons, pentimento has got some potential if you have strong totem build
I've been using pentimento with the new scourge perk, lullaby and thrill of the hunt and I had quite a decent sucess with it.
Due to totems taking quite a bit extra time to cleanse, survivors at least break 1 hex totem per game rather than booning it. If they don't then they have lullaby on their ass which is pretty strong perk after you get like 3 hooks. Even good survivors start missing skill checks, because they are simply not used to the delay in sound notification.
However you can replace lullaby with any other hex perk that is strong in general and survivors always want to get rid of it.
