Slug Lord
Slug Lords can be found in the Deep Jungle and are also spawned by Slug Mothers if you damage them or wait too long. These flying enemies approach the player and shoot somewhat fast projectiles that deal damage and inflict +10% Poison; running into them will also cause the player to take damage.

Slug Lords are replaced by Luminescent Slug Lords on Challenge Level 1 and above. These enemies, found either wandering around the Deep Jungle or spawned from Luminescent Slug Mothers, have much more health and damage and also shoot faster projectiles than their lesser brethren, making them a greater threat than before.
