Agent 2

The Ouroboros Sprayer is a Hardmode gun weapon which can either be dropped by the Wall of Flesh rarely, with a 2.45% rate, or crafted. It shoots a spew of 3 circular dragon-like sprites that latch onto enemies and visually squeeze them, dealing 59 damage per 2 seconds. After 10 seconds- or the enemy has been killed- they sprout small wings and can be seen flying back into the gun.

Obtaining
The Ouroboros Sprayer can be obtained by, as said before, defeating the Wall of Flesh or crafting it.

Crafting
It can be crafted through the use of 30 Palladium Bars, 10 Dragon Scales and a Hoop Morph at a Tinkerer's Workshop.

Trivia

 * In real life, the ouroboros is the sign of a dragon, serpent or snake-like figure swallowing its own tail in a circular form to respresent wholeness or infinity.
