Tl;dr at the end.
I’ve been thinking a lot of Empower as the main CW ability and I just can’t bring myself to support it. The ability just does so much and so little at the same time, I don’t think it will actually solve any problems currently plaguing the CW.
The biggest problem with Empower us its reliance on others. In a game on deceit, of course not every claim will be trust worthy. The sheriff or butler claim could just be an unseen or cult member and using you to stop more key bd roles. While you can just say it’s good on the evils for tricking him, this will lead to a lot of uselessness feeling when the CW realized later they were tricked.
Which leads me to my next point of the ability feeling useless. Basically every single ability in the game gives some kind of feedback. Whether you find an unseen as sheriff, or physician finds no one attacked their target or even finding yourself prevented from visiting someone. Something happens. But with Empower, you get no feedback. It doesn’t help that multiple classes (Prince, CW, physician, noble, mystic, and Hunter) all don’t benefit from Empower at all. This leaves only knight, butler, drunk, Princess, sheriff/paladin, and observer. Add in investigators only benefit from it if they happen to be targeted by illusionist or run into a fool or scorned. Not situations that happen every single game. With butler and drunk, you’re at least ensuring they occupy their target and knight gets an assured kill (assuming he attacks evils) but the CW is still left in the dark about all of it. Did his ability help any? Did your target actually do anything that night? CW just doesn’t know.
Now granted the ability has the potential to make huge plays, such as csing or occupying the possessor or mm. But i feel these situations will be so far and few between, that it won’t matter. This situation requires both a CW and a butler/drunk/knight and a night immune target. If even one of these requirements aren’t meant, the ability will have been useless.
Tl;Dr The game needs to be in such a simple game state, that the CW knows his target is compatible with Empower and that using Empower wouldn’t have already given them the same results. The ability has fringe application at best, and will do absolutely nothing to make CW more interesting to play.
