Arduin summons a shield that has 12% of his own maximum HP, which lasts for 5 seconds. When the shield is summoned, Arduin deals 200 magic damage to surrounding enemies. Within 8 seconds of summoning his shield, Arduin's next 3 normal attacks deal an additional 100 true damage, and each time his normal attacks damage an enemy, the cooldown time for Cull is reduced by 1 second.
