Crypt Witherlord Sword

The Crypt Witherlord Sword might be a future  Dungeon Sword. The sword has never been obtainable, but may be added in a future update as it still exists in the Essence Guide. It can be upgraded using Wither Essence and appears to be an upgraded form of the Dreadlord Sword, although the ability worked differently as The Dreadlord Sword's ability at one point had a cooldown.

Its ability is identical to the Mega Walls Dreadlord class skill.
