Wither Beast

The Wither Beast is an enemy from the Old One's Army event. When within 25 tiles of a player, it will surround itself with a 50×50-tiles aura of crystals, visually similar to the Dryad's Blessing, inflicting the Withered Armor debuff, which halves defense. The debuff will dissipate immediately after leaving the aura zone. Eventually, the Wither Beast will enter a state where it will remain stationary until it is killed. It will also regenerate its health when damaged.

Along with the Etherian Lightning Bug, it is one of only two enemies in the event that require the usual 50 kills to receive the respective Banner.

Trivia

 * The Wither Beast is very similar in color and stature to the Evolution Beast from the Lunar Events.
