Hardlight blade

The hardlight blade is a Forerunner melee weapon composed entirely of hard light. It is affixed to the arms of the Promethean Knights of Requiem.

Gameplay
The blade performs similar to an Energy Sword in that it can strip away energy shields and cut through armor with relative ease. The blade is unwieldable to players as the weapon disintegrates immediately after the Knights are defeated. However, it is usable by players when they are assassinating a Knight.
