I thought damage was a little high before, but that was before sigil nerfs.
With the sigil nerfs I feel it is a little to low now, and the game never got to see any longevity of the middle ground.
I think it should at least added to “Imagined Burden” since it would disallow for the use with “Mental Anguish” or “Power block” which could be considered an aspect of it’s balance, as well as making the less popular trait more appealing.
Very good idea, IB is the perfect place to put it.
