The enchantments giving life to the Elemental Lord burned, the power he had painstakingly accumulated leaked, and the damn ochre Griffon hammered at him with a heavy mace the moment an opening in his defenses appeared.
With her 40 meters (132') of height, Rethia was half the size of Argantyr. Yet the Davross of her mace and the Life Maelstrom boosting it and her physical might more than made up for it.
On top of that, after infusing her husband and his twin sister with the silver lightning as well, the Flames of their combined attack reached the destructive power of a natural disaster.
Bringing the Elemental Lord down wouldn't have been difficult for them, especially with Surtr's and Rethia's children helping them from the backlines. Their Origin Flames pierced through Argantyr's barriers while Life Maelstrom overloaded them.
