so uh does any1 know how to make a dice pool? like what celestial warlock has? im trying to make a feature for a subclass thats bassically just that but it aint working, it lets me remove multiple things at once, but doesnt also roll the dice at the same time

does any1 know how to actually do it or is my best bet to do the dice rolls manually?

Edit: adding more context, im also trying to make another feature for the subclass that just recovers some of the lost dice pool plus some other stuff but thats doable in terms of doing it manually
