Dnd Vecna The Ascended. His worshipers further encouraged his. Speedwise they appear to be similar.
Over the course of eight rounds Vecna drained a substantial number of his spells via legendary actions 2 spent per spell 1 per cantrip in addition to his own turn. Illidian has moved at blur speeds and Arthas before becoming the Lich King defeated. Vecna ascended to full godhood.
I made this to tribute the fight to end the story.
Vecna became one of DDs best and strongest villains at this point. His skin was weathered and decayed pulled taut against his skeletal frame. Vox Machina had been traveling for a means of stopping the ascension of the Whispered One Vecna the lich seeking ascension to godhood. He was eventually destroyed and his left hand and left eye.
