Ooma

Behavior and Tactics
It floats up and down in place in a set pattern.

Its body bursts when hit, revealing its orange volatile core. After a brief moment, the core homes in on The Knight, exploding on contact with the player or a wall and dealing 2 masks of damage.

The core is tricky to avoid due to its travel speed, so it is advised to mainly avoid attacking Ooma when possible, as they are otherwise passive.

A direct hit from a Vengeful Spirit or Shade Soul projectile will continue pushing the explosive core along its path, often until it hits a wall and explodes. This is the safest way to destroy an Ooma but requires SOUL to be spent.

Another way to destroy them without having to deal with the exploding core is by using acid. If an Ooma is pushed into acid, (via a nail strike from above), the core will be harmlessly destroyed along with the rest of the Ooma. Unfortunately, this method of killing does not allow you to collect Geo from the kill.

It is killed by a single tick of poison, so using Defender's Crest and Spore Shroom as well as Glowing Womb is not recommended when traversing its territory.
