I tried to have Astarion cast the spell. It gets read and he has the 3 images around him but he has no valid targets and the pick-a-race never pops up.

One of the things I was thinking it should do it pick a random NPC in the area and copy them. Or pick the majority, I don't know. But doin a grab or a "copy" of the one you want to talk to would be divine.

What is the problem you are solving? Does your proposed change solve the problem? Is your change feasible? What else will be affected by your change? Will your change impact revenue? Does your change align with the goals and strategies of the organizations (Larian, WotC)?
