See the Invisible

Objectives
Collect 8 batches of Cursed Ooze from the Ruins of Constellas.
 * Cursed Ooze (item) (8)

Description
Yeah, yeah, your stuck-up mage friend there hit it on the nose. The imps over at Shadowlurk Ridge are hiding the key to the satyr's barrier in the nether. It's right there, but you can't see it or touch it unless you're shifted.

I guess you're out of luck though, because only imps can phase shift! So you should just close your eyes, turn around, and let me go...

It was just a joke! Don't hurt me! I'll need slime from the cursed oozes around these ruins. Bring me enough to cover you from head to toe!

Rewards
You will also receive:

Progress
You got that slime?

Completion
Oh good, you're back! Don't leave me alone with her! She's crazy!

Gimme that, I'll have you seeing the invisible in no time!
