Effects[]
Sincerest Form of Flattery allows you to become a duplicate of another creature you can see. This effect follows the rules of the Polymorph spell, except you also assume the alignment of the creature you duplicate. This effect lasts until you choose to end it, 1 minute passes, or you are reduced to 0 hit points, as per the Polymorph spell. Roll a d20. On a 5 or lower you instead transform into another random creature you have seen within the last minute.
