Weapon and Armor Proficiency: Arcane tempests do not gain any proficiency with weapons or armor.
Arcane Precision (Su): An arcane tempest may add his Charisma modifier, up to his arcane tempest levels, as a bonus on his ranged attack rolls.
Bonus Spell (Ex): At 1st, 3rd, 5th, 7th, and 9th level, an arcane tempest learns one additional spell of any level up to highest level known.
Runic Study (Ex): An arcane tempest is able to cast spell completion and spell trigger items, such as scrolls and wands, as a wizard of level equal to his arcane tempest level.
Imbued Runes (Su): At 2nd level, an arcane tempest gains the ability to place a spell with a cone, cylinder, line or sphere area of effect upon a rune bullet fired from his pistol. When the bullet is fired, the spell’s area is centered on the square where the bullet
hits, even if the spell could normally be centered only on the caster. This ability allows the gun mage to use his pistol's range rather than the spell’s range. It takes a single standard
action to cast the spell and fire the rune bullet. Unlike touch and ranged touch spells, the imbued rune bullet must be fired in the round the spell is cast or the spell is wasted. If the shot misses, the spell fizzles.
Flash Fire (Su): At 4th level, an Arcane Tempest gun mage gains the ability to fire a rune bullet at any target in his range. This attack ignores concealment and cover, but not total concealment. The gun mage must be able to see his target but does not need line of effect, and the bullet can pass through any non-magical obstacle in its way until it reaches its target. An arcane tempest may use this ability a number of times up to his Charisma bonus per day.
Arcane Trigger (Su): At 6th level an arcane tempest gains the ability to fire his pistol even if he is not wielding it (pistol can be up to 30 feet away). An arcane tempest may use this ability a number of times up to his Charisma bonus per day.
Ricochet (Su): At 8th ability the arcane tempest gains the ability to make a second attack against a nearby target after hitting his first target. A number of times equal to his Charisma bonus per day the gun mage may choose to make a second attack against a target within 10 feet of the first target. Each attack does normal damage, but only the first target is affected by any spells attached to a rune bullet.
Penetrating Sight (Su): At 10th level, an arcane tempest gains the ability to, as a free action, see even in total darkness and magical darkness, to see invisible creatures or objects normally, to see the exact locations of creatures or objects under blur or displacement effects, and to see into and through solid matter when using his pistol. Penetrating sight can penetrate one foot of stone, one inch of common metal, or up to three feet of wood or dirt. Thicker substances or a thin sheet of lead blocks this ability.
An arcane tempest may use this ability a number of times up to twice his Charisma bonus per day.
