I’ve never played DND so I don’t know if this is something you could pull off or anything but I’d probably be like
“I snort the fine pile of dust” and then, I don’t know, there’s some latent personality or intention there, so now we have to alternate playing my character between turns/minutes or something. It’d probably make for some great RP moments, especially if each personality couldn’t remember very well what the other was doing previously. Maybe the class and abilities change with each person, which makes arming up appropriately interesting or a pain depending on how we handle it I suppose.
Doubtful either will do anything but maybe make a report that might be ready if they are murdered. Cops will say there is nothing they can do because nobody is hurt. I’d bet a field agent would never call you back or show up.
