The Sunfire spell allows the wizard to create an explosive burst of flame around himself.
A Sunfire is like a Fireball: An explosive burst of flame, which detonates with a low roar and delivers damage proportional to the level of the wizard who cast it: 1d6 points of damage for each level of experience of the spellcaster (up to a maximum of 15d6). The wizard gestures with his hand and the entire area around him erupts in flames, striking all except for the caster. Creatures failing their Saving Throws each suffer full damage from the blast. Those who roll successful Saving Throws manage to dodge, fall flat, or roll aside, each receiving half.
