The allied forces had never stopped raining powerful spells upon the lost city, but now each spell left a deep mark on Ruugat's stone body.
The last Fountain of Death had consumed much of his energy reserves, and, in his current state, Earthly Vault had lost part of its effectiveness. The white flames were the natural counter to earth-based abilities, and they burned at Ruugat's protective aura, weakening it further.
Tier five spells were supposed to blow open castles and destroy entire city blocks, but, until that moment, they had been ineffective against Ruugat's sheer size and the impregnable defense of Earthly Vault.
Without it, every Raging Sun opened a molten crater. Every magical formation bent the metal and cracked the black stones that formed the lost city's body. For the first time since the beginning of the fight, the attackers hurt Ruugat faster than he could repair himself.
