Agony was a Lv. 3000 Raid Boss that appeared in the Party Realm. He alternated spawns with Ashen and could revive into a much stronger Tormented form, making the second phase significantly more dangerous.
The following message appeared when the boss spawned:
"Pain takes form at the Colosseum."

Spawning:

• Spawned every 20 minutes in the Grand Colosseum, alternating with Ashen.

• Despawned after 9 minutes if not defeated.

• Revived into a Tormented Boss when reaching low HP, increasing health from 55,000 to 200,000.

• Defeat/despawn message: "Pain recedes."

Unique Drops:
Summer Token

Tips:

• After reviving, Agony's HP increases from 55,000 to 200,000, while the x3 max damage cap allows players to defeat him more quickly.

• Tormented Agony attacks nearly three times faster than his normal form, making him much more dangerous.

• Since the Grand Colosseum is a PvP zone, fighting in a private server is recommended. PvP is automatically enabled upon entering the arena.

• Bomb [V] – Self Destruct is very effective, as Agony often stays close while the move charges, allowing it to deal massive burst damage.

• Buddha or fruits with good range and strong PvP performance are recommended for this fight.
