Yet not a single one of them fell.
The shaman's black robes shattered, revealing their diverse forms. Flames scorched their flesh and skin as rocks grew from their flesh, their bodies transformed into nothingness by the gales and the surging waters.
These high-ranking shamans let out mournful screams, as the spells they cast exacted a heavy toll on them.
[Shaman Forbidden Spell: Elemental Incarnation!
Spell Description: Sacrifice your flesh and soul to incarnate as a powerful Elemental. You will completely lose your human form and exist in the world as an Elemental being.]
This was a taboo spell created by the shamans of the ancient Shadowmoon Sect in Draenor, and it was frequently used during the ancient wars of Draenor.
However, because the shamans that turned into elementals often fell into madness due to the psychological pressure from the transformation, the spell became forbidden.
As a successor of the Shadowmoon Sect, Ner'zhul naturally mastered this forbidden spell.
