Etherian Lightning Bug

The Etherian Lightning Bug is an enemy from the Old One's Army Event that spawns only in tier 3 (post-Golem), in the event's second wave.

It shoots that deal high damage (100 /  / ) and inflict the Withered Weapon debuff, which halves player-inflicted damage.

It is one of only two enemies from the Old One's Army that requires only the usual 50 kills to obtain its corresponding enemy banner, the other being the Wither Beast (most other enemies from the event require a higher kill count). Like all Old One's Army banners, it is purely decorative, and does not provide buffs.
