Call Drunken Priest - This summons a drunken priest, obviously. A "battle-mage/healer" kind of priest and not a regular religious man. So he'd have a variety of buffs and heals and such.
Incantation of Conjure Barbs- Vines with barbs on them (like bramble) coming out of the ground to either hold a person or create some bad terrain/trap
Dexterity Deflection- Dodge an attack, and send its effects back at the opponent
Crafter's Blast of Earth- "Blast of Earth" refers to obviously shooting out earth. Can use this to take any ground around him and use it as a projectile. "Crafter's" allows him to shape the earth into any kind of shape that he wants want before he shoots it out.
Unknowable Hex of Fortification and Viciousness - A buffing move that is independent of his knowledge, but while helpful to him is harmful to the opponent in some way.
Rains of Force- Basically shoots out a rain of vague magic that has a heavy heft or gravity to it, if that makes any sense.
Elemental Sun of Nothing - Obviously, I see this as a huge and intensely powerful magic attack with the potential force of a black hole
Dexterity Deflection is a potential answer to Accuracy Control. He simply gets out of the way of the attack after it has been aimed and fired at him. Unknowable Hex of Fortification and Viciousness is a passive ability that lets Ganon actually survive attacks rather than be a glass cannon. It will take more than one or two direct hits of Greater Casting of the Thunderous Chain to take him out. Elemental Sun of Nothing is still the ultimate offensive spell in RST. Strong enough to overwhelm any defense and a huge area of effect so it is undodgeable.
