Pacifism bomb

This volatile, translucent green liquid is contained in a spherical glass vial. A character throws it as a ranged attack on an opponent. On a hit, the glass shatters and the mixture immediately becomes gaseous. The target puts down their weapons and sits in passive protest for 1d10 rounds. During that time, they will not attack or move. At the end of their pacifist rounds, it costs them an action to pick up any weapons and half their movement to stand.
