Level: Sorcerer 3, Wizard 3
Components: V, S, F
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: 10 minutes/level or until discharged
As you clasp the shell in one hand and the ball of sap in the other, a silver radiance flecked with blue lines surrounds you. You pocket the items, but the radiance remains.
You gain damage reduction 10/magic against ranged weapons. (This spell doesn’t grant you the ability to damage creatures with similar damage reduction except as noted below.) Once the spell has prevented a total of 10 points of damage per caster level (maximum 100 points), it is discharged.
If any projectile fired from a ranged weapon that strikes you has all its damage negated by your damage reduction (10/magic), the projectile is turned back upon the creature that fired it. The attacker’s attack roll is used to determine if the reversed projectile strikes the attacker, but the damage is rerolled. If the attacker is also protected by a reverse arrows spell, it is possible for the projectile to bounce between both individuals until one of the spells is discharged from accumulated damage.
Focus: A piece of shell from a tortoise and a ball of tree sap.
