Moon-Mad Terror

Your hybrid form becomes a nightmare silhouette. Hostile creatures of your choice in the emanation must make a WIS save or become frightened for the duration. A frightened creature repeats the save at the end of each turn. A creature that succeeds is immune for 24 hours.

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