Uumuu

Behaviour and Tactics
Uumuu floats around the room, occasionally using one of two attacks:
 * Volt Overdrive: creates bursts of lightning in random locations. The player must avoid them before the bursts fully erupt to avoid getting hurt.
 * Volt Focus: creates bursts of lightning at the player's location in quick succession. It is imperative to constantly keep moving as long as this attack is going on to avoid getting caught in the lightning.

Uumuu cannot be harmed normally, as its vulnerable core is protected by a membrane that deflects the player's attacks and shields it from Spells. However, after dodging attacks for a short time Quirrel will appear to help the player, leaping around the battlefield and occasionally popping Uumuu's shield. This will deflate Uumuu, leaving it open to attacks for a few seconds.

Although Uumuu may only have two attacks, they're both quite hard to dodge, and their pattern leaves few opportunities for healing. In addition, Uumuu's erratic movements and the very sparse opportunities for hitting it compared to its health pool result in a very drawn-out battle.

Get in as many hits as possible when Uumuu's shield is popped, and be prepared to dodge an attack right after. In desperate times, this can be an opportunity to heal instead. Avoid jumping in the water below a platform in the arena, as this greatly slows movement.

As with most boss fights, Quick Focus is highly recommended. SOUL-generating charms like Soul Catcher/Soul Eater, Kingsoul, and Grubsong are also very important in this fight, as chances to hit Uumuu and consequently to gather the SOUL needed for healing are quite rare. Great Slash and a Pure Nail are recommended in order to make short work of Uumuu.

Trivia
The Uumuu fight is one of two fights in the game where an NPC aids the player, the other is the Traitor Lord fight, where Cloth joins in if her questline was followed.
