Angry Face

Angry Face is a cursed sidequest item from the Paper item set that flips the wearer to the enemy faction. The cat spawns near your team, automatically moves and uses an ability each turn with no player input, and can still gain level ups even while downed. After each battle it fully regenerates. The sidequest objective is to deal with this rogue cat — completing it rewards the Happy Face, which keeps the aggressive spawn-near-enemies positioning but replaces the faction-switch with a more manageable AI-controlled bonus turn.

The faction flip means the Angry Face wearer actively attacks your own party every fight. They cannot be controlled, heal fully between battles, and continue to level up, meaning they grow stronger over time if the sidequest is prolonged. This creates a persistent hazard that your team must work around or through every combat. The AI controlling the rogue cat is not sophisticated, but a fully leveled, self-healing enemy is still dangerous.

The only strategy for Angry Face is to complete the sidequest as fast as possible. Build your team to handle the rogue cat quickly at the start of each fight before it causes damage to your party. The rogue cat is a fourth faction of one, so AoE abilities that hit everyone or abilities that down units quickly are the best tools. Happy Face's controlled aggression is a major upgrade over the uncontrolled enemy you managed during the sidequest.
