Skills: Spellcraft (As this is already a class skill you automatically have maximum ranks in Spellcraft without investing any points into it. If you have already invested points in it you may reinvest those points.
Your mastery of all things magic gives you a keen insight into the spells that other people weave.
Arcane Barrage: (0 mana, signature spell) As a full round action, you may make one ranged touch attack against each enemy within 10 feet/ 5 levels of you. This spell deals magic damage equal to your modifier +1d4/5 levels beginning with level 5.
Arcane Sanctuary: (15 mana, signature spell) As a standard action you may activate a field that absorbs the energy of spells. Spells cast against you have a 10% chance/5 levels to fizzle and grant you mana equal to the mana invested in the spell.
Counterspell: When you delay your turn, you can interrupt another casters turn to counter their spell.
