Thera’s Bane is a new ability that Kratos acquires in God of War: Ghost of Sparta. He rips this power from the chest of the TitanThera as he frees her from her prison beneath the volcano of Atlantis. It has the ability to engulf the Blades of Athena in fire. It greatly increases the power of the blades, and it allows Kratos to implant searing cores into his enemies which will explode after a few seconds. It also destroys the shields and armour of various creatures. Thera's Bane can be used to open damaged doors by placing a Searing Core in the center of the door, causing an explosion. It makes the colour of the blades of athena black and red.
While using Thera's Bane, Kratos will not stagger when hit by attacks from enemies, but remains vulnerable.
Some enemies, including Thanatos and Erinys, wore armour that rendered them invulnerable to all attacks. Kratos was only able to defeat them by using this ability against them, to destroy their shielding.
In the final battle, the death of Deimos spurred Kratos' rage to such heights that the Blades of Athena became engulfed in Thera's Bane for the remainder of the battle.
