I'm trying to make a homebrew weapon here that gains a bonus to attacks/damage based on the number of charges it has, and theoretically the item can have infinite charges.

I'm very aware of how unbalanced that sounds but I've added consequences for holding charges but that's not the point of this thread lol.

Is there a way for the homebrew system here on DnDBeyond to tie attack/damage rolls to charge count? Additionally, is there a way to not have a set limit on an item's charges?

Unfortunately, the answer to both questions is no.

Oh well, I'll just have it kept track of in the Notes or something. Thanks!
