Shadow crystal is one of the crystals that power Nex in the Nex: Angel of Death fight.
The crystal is attackable when Nex reaches 600,000 life points. It can only be attacked depending on the order of the praesul (Nex's mages) were killed. While this crystal is active, Nex is able to cast shadow traps underneath several players, which deal heavy, typeless damage while they are standing on the shadows. Multiple shadow traps are placed for each affected player, so they will need to keep moving to avoid taking damage. These traps will also harm other players if they stand on it too long.

- The pillar it resides on has its own examine, which reads as "The pillar contains a sliver of crystal so dark it appears to drain the light around it."
