Pinkymod/Demon Archer

The Demon Archer is a Pre-Hardmode found in the Underworld. It will fly towards the player until they are in range of its bow, after which it will remain stationary while shooting Hellfire Arrows.

Bestiary Entry
Denizen of the underworld. Not all demons are formed magically adept - some just cannot pick the demonic arts up at all. To compensate, they are given bow and arrow to make up with their lack of natural weapons. As there is a fierce competition in the underworld, many Demon Defenders will practice vigorously until their arrows hit as hard - or even harder, than their magic-wielding kin.
