In their desperation, the spirits tried to blast Treevor with their incomplete spells, increasing its power by force using its core's mana and accumulated energy.
Dozens of corrupted element spells attacked them in response, blocking most of their attacks. Wizard and wyvern slayers did not have the same limitations as spirits and could cast spells with even more power within the field of the dead.
Few spells got through and hit Treevor, but a barrier of dark amber stone easily blocked it. Treevor was weaker than the spirits, but between the incomplete spells and the constant supply of amber energy he received, the balance of power tipped for Treevor.
The wyverns flew over the spirits and breathed the dragon's breath over them, before the mage-slayers leapt from their backs and engaged them in hand-to-hand combat.
