The Crypt Witherlord Sword was a planned EPIC Dungeon Sword. The sword was not obtainable, but it was listed in the Essence Guide. It could be upgraded using 
Wither Essence and appeared 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.
