I created a weapon for a player that allows them to add 1/2 their proficiency bonus (rounded down) to WIS and CHA saves. I know I can manually change to a flat number on the Abilities & Attributes page, but there's gotta be a formula I can use instead. Unfortunately I'm getting stuck on the order of operations/parentheses. Help? So far, I have: (@{pb}+[floor{@{pb}/2}]) I know that curly brackets have special meaning in Roll20, so is there a way to go about this?
