Theresis' power is all magic, which enables her to cast spells of every kind. From invisibility and teleportation to fire magic and summoning demons, Theresis' magic is both vast and powerful. She uses a wooden staff to channel her magic, and she always carries a few enchanted objects -- a ring of water control, a necklace that enhances her speed and strength, and a wand of lightning strikes, which she can wield with deadly efficiency.
