First thing I wanna get out of the way, I'm not here telling anyone that charm needs to stay the way it is, even if all the other precepts literally doubled the damage a player can do, charm would still see use, it's that good.
Change whatever you feel like needs changing about it.
But I do have 1 small request, in case the resource buff stays in one way or another.
Please let it allow to stack, just like charm currently can do.
Getting a double, triple or even higher buff is one of the most satisfying things there is, and statistically it's uncommon enough to not really make any big dent in to the amount of resources collected over a large enough sample size.
It is simply just satisfying to see that 16x or 32x steel essence popup once a month.
