Wandering Vagrant

Field Notes
Day 3. While looking though some wreckage of the old ship. I felt hot sensation all over my skin and a brilliant white flash. Over the horizon maybe 5 miles north I saw it, looming over the forest tops.

It must have been the size of a house, this thing. A massive variant of the jellyfish seen earlier; this behemoth hovers in the air, searching for something. The gas used to propel this beast bend the trees below it flat. When it spotted its prey, it sent out six bioluminescent orbs, all crashing towards the ground and incinerating the target.

This Vagrant, as I've come to call it, seems to wander amidst the skies, followed by many jellyfish. On occasion the clouds part, I swear I sometimes see hundreds of vagrants up there. What are they looking for?

Tactics
The Wandering Vagrant only deals damage through the nemocysts (bioluminescent orbs) that it shoots out, which are propelled outward and then streak toward the player. By simply moving, you can avoid all damage from this boss. It doesn't use its attack often, making it a very easy boss; just keep moving and shooting if you're a ranged character, and if you're a melee character, just stand on it, using your attacks, and then move when it shoots.

Trivia
The Wandering Vagrant may be a reference to Homestuck, an online webcomic, as it contains a character with the name "Wayward Vagabond", whom at a point is both searching for something and spending some time in the sky, so to speak.
