Low-chief Sugumu from Jahra is the petitioner here. He asks you to eliminate Enkelados, because he destroys rare flowers that can be found only on Ozmone Plains.
About 18 000 HP
Resistant to Libra,
You can find Enkelados on the same area where the entrance to Henne Mines is, but to make him appear you have to kill all Wus there - fortunately there's not much of them. There might be a small problem in the form of two Rare Mobs that appears on this area - Aeros and Bull Crock. If they both attack you at the same time (which is possible) don't fight - just reload the game.
Tactic: Berserks and healing.
His attacks are: Spin Kick - deals damage to all characters standing around him, Restore - recovers some HP, Purify - he becomes immune to every bad status change, Berserk - cast on himself at the end of the battle.
Bounty: 1100 gil, Ether, Golden Amulet
