/*:://////////////////////////////////////////////
//:: Name Spell Turning Include
//:: FileName SMP_INC_TURNING
//:://////////////////////////////////////////////
This includes the functions to let spells turn back from the target
to the caster!
From 3.5 rules:
Spell Turning
Abjuration
Level: Luck 7, Magic 7, Sor/Wiz 7
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: Until expended or 10 min./level
Spells and spell-like effects targeted on you are turned back upon the
original caster. The abjuration turns only spells that have you as a target.
Effect and area spells are not affected. Spell turning also fails to stop
touch range spells.
From seven to ten (1d4+6) spell levels are affected by the turning. The
exact number is rolled secretly.
When you are targeted by a spell of higher level than the amount of spell
turning you have left, that spell is partially turned. The subtract the
amount of spell turning left from the spell level of the incoming spell,
then divide the result by the spell level of the incoming spell to see what
fraction of the effect gets through. For damaging spells, you and the caster
each take a fraction of the damage. For nondamaging spells, each of you has
a proportional chance to be affected.
If you and a spellcasting attacker are both warded by spell turning effects
in operation, a resonating field is created.
Roll randomly to determine the result.
d% Effect
01-70 Spell drains away without effect.
71-80 Spell affects both of you equally at full effect.
81-97 Both turning effects are rendered nonfunctional for 1d4 minutes.
98-100 Both of you go through a rift into another plane.
Arcane Material Component: A small silver mirror.
