Predatory Mimicry

Choose one creature you have studied within range. It must make an INT save. On a failed save, it loses access to one action, one bonus action, one reaction, and one non-unique passive trait you have seen it use. You gain those features as imprints for the duration.

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