Open your eyes to the darkness, and drown in its loveless embrace. The gods will not be watching.
Shadow Blade is an ability used by The Thunder God during the third boss fight of the Orbonne Monastery 24-man raid dungeon, as part of the Return To Ivalice storyline. The attack targets one or two people from each of the three alliances in the battle, causing them to drop an expanding globe of dark energy at their location after a few seconds, which will damage everyone inside it over time. If two of these globes overlap as they expand, they will explode, dealing heavy damage to every person in the battle, and inflicting a Bleed debuff that deals further damage over time.
