Wandering Vagrant

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.Wandering Vagrant
