The Nightmare Wizard is the Nightmare wizard boss that players have to fight.
This wizard, like others, will pursue the player through the whole Nightmare Kingdom until he is defeated in his own realm. Each Nightmare Kingdom has own wizard but they all looking the same. He appears to be inspired by H.P.Lovecraft creatures, head resembles squid and tentacles coming from mouth and bottom, and sometimes he has white orbs with him.
After defeating the wizard boss in his realm, the player receives a black orb as a reward. Players can fight this boss only once. To reach to his realm a player must complete all locations in the kingdom and procede to the final Time Portal.
