Shadow Weave Magic [General]
You have discovered the dark and dangerous secret of the Shadow
Weave.
Prerequisite: Wisdom 13+ or patron deity Shar.
Benefit: From now on, your spells tap the Shadow Weave instead
of the Weave. You also can activate magic items that use the Shadow
Weave without taking damage.
Add a +1 bonus to the DC for all saving throws of spells you cast
from the schools of Enchantment, Illusion, and Necromancy, and
spells with the darkness descriptor. You get a +1 bonus on caster
level checks to overcome spell resistance for these schools and spells.
The Shadow Weave proves less than optimal for effects involving
energy or matter. Your effective caster level for spells you cast from
the schools of Evocation or Transmutation (except spells with the
darkness descriptor) is reduced by one. (First-level Shadow Weave users
cannot cast spells from these schools.) The reduced caster level affects
the spell’s range, duration, damage, and any other level-dependent
variables the spell might have, including dispel checks against you.
You can no longer cast spells with the light descriptor, no matter
what your level is. Such spells automatically fail. Your ability to use
magic items that produce light effects is also limited—you cannot
invoke an item’s light power if the item’s activation method is spell
trigger or spell completion.
From now on, any magic item you create is a Shadow Weave item
(see Chapter 2: Magic).
Special: Knowledge of the Shadow Weave has a price. When you
acquire this feat, your Wisdom score is immediately reduced by 2
points. If this loss or any future Wisdom loss reduces your Wisdom
score to less than 13, you still have the feat. (This is an exception to
the general rule governing feats with prerequisites.)
Restorative spells (such as restoration or greater restoration) do
not reverse the Wisdom loss. You can, however, strike a deal with
Shar, the goddess who holds sway over the Shadow Weave, to regain
your lost Wisdom. You must receive an atonement spell from a cleric
of Shar. Sharran clerics require the subject to complete a dangerous
quest before receiving the atonement, and afterward you must choose
her as your patron. (The usual quest is to destroy a follower of
Selûne whose level is at least as high as yours.) If you later change
your patron, you immediately suffer the Wisdom loss. If you take
Shar back again as your patron deity, it is not regained.
