As long as Glaive’s Immunity is active, Corvus Glaive cannot die. Instead of dying, 4 Glaive charges are removed. If Corvus performed a Well Timed Block against that attack, 2 Glaive charges are removed instead.

If Corvus is able to spend all of his Glaive charges in less than 30 seconds since they were first activated, the cooldown to get them back is reduced by X%.
