Wizards who specialize in an elemental arcane school can further refine their studies by choosing a focused school.
Wizards who choose a focused school keep the bonus spells from their elemental school and must select an opposition elemental school as normal, but a focused school replaces some of the powers granted by their elemental school. Once a focused school is chosen, it can’t be changed.
Associated Schools: Earth, fire.
Magma Furrow (Su)
As a standard action, you can send forth a 20-foot line of magma. Any creature in this line takes 1d6 points of fire damage + 1 point for every 2 wizard levels you have. A successful Reflex save (DC = 10 + half your wizard level + your Intelligence modifier) halves this damage.
In addition, the ground in this area remains molten for another 1d4 rounds. Creatures that begin their turns in the area can move out that turn without penalty, but those that enter the area each take 1d6 points of fire damage. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.
Lava Shield (Su)
At 8th level, you can create a barrier of lava to protect you for 1 round as a standard action. Choose one edge of your space. That edge is treated as a solid wall for attacks targeting you only. You gain total cover from attacks that pass through this edge, and you gain the benefits of fire shield (warm shield) while adjacent to the lava shield. You can dismiss the lava shield as a free action, and it disappears immediately if you leave your space. You can use this ability a number of rounds per day equal to half your wizard level.
