The Crypt Blade is described to be a blade that resembles similar to that of a scimitar. It has a purple gem at its hilt, possibly retaining the power the blade once held. The blade's color is dark purple, with lighter tints and shades seen on specific parts of the blade.
The special ability of the Crypt Blade is titled 'Critical Rush', which, upon activation, will release a stronger forced swing towards the opponents in front of them, depending on how much melee damage bonuses the player has. The cooldown of the special ability lasts for 10 seconds before it can be used again, making it quite easy for players to activate the special ability to eliminate waves of opponents.
- During the Balance Update [v1.31], the Crypt Blade's base damage was increased from 400 to 500 points.
