Defeating Paintmaster Sheo on Radiant difficulty in the Hall of Gods for the Godmaster DLC. Radiant difficulty increases the boss health and some minor tweaks (Sheo doesn't appear to gain anything over the easier difficulties), plus you die in one hit. One of the easier new bosses, but the design for it is awesome. Fingerpaint fight go!
