Undo Transmutation

When a creature or object within range is altered in size, material, density, form, texture, petrification, polymorph-like shape, or object state, attempt to stabilize it. Make an INT check against the effect DC. On success, suppress the transformation until the start of your next turn or end it if it is Tier 5 or lower.

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