Zachary S. said: I have no api scripts running. It does change it on the npc sheet but only when I apply the formula to the token? for the attribute. I am using VTT option for roll hit dice. I suspect you're talking about using the 3rd party extension Beyond20? Perhaps? If you are, I just checked on the Beyond20 Discord channel (quickest way to get to the author), and it is as I suspected. There is no way, currently, to adjust HP on monster/NPC tokens on the fly using Beyond20 as the glue between DnD Beyond (DDB) and Roll20. They are looking at using the DDB encounter manager/combat tracker to pass information to Roll20 tokens, but so far, it only syncs initiatives.
