Casting You deliver touch spells using a melee weapon.
Benefit: When casting a spell with a range of touch, you may deliver the spell using a melee weapon or unarmed attack as a free action during the same turn.
Special: Though there is only one attack roll, the spell does not share the weapon’s critical range or multiplier. Instead, the spell uses the standard profile (critical range 20, ×2 damage). If both spell and weapon threaten a critical, roll each confirmation check separately.
