Legendary Trickster

Trickster. The battlefield becomes a con. For the duration, once per round you may impose one dirty trick on a creature in the emanation that fails a DEX or WIS save: blinded, prone, no reactions, drops an item, attacks the wrong space, or triggers a trap or hazard you prepared.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
