D&Dtools

To employ this spell, you must succeed on a melee
touch attack against an undead creature. If you do
so, your touch deals 1d6 points of damage per two
caster levels (maximum 15d6). This damage represents
negative energy that you draw from the subject,
resulting in a ball of writhing shadow you hold in your
hand. You can use this ball of negative energy in one
of three ways.
You can, in any following round, touch any other
undead creature with that negative energy, as a standard
action. The undead creature absorbs the energy,
healing as many points of damage as you dealt
to the initial subject, up to the new subject’s normal
maximum hit points.

• You can use the ball of negative energy to make a melee

touch against a living creature, dealing the same
amount of damage you initially dealt.

• You can use it to power a rebuke undead attempt. The

next rebuke attempt you make, so long as it occurs
before the spell’s duration expires, does not count
against your daily limit.
The ball of negative energy dissipates in 1 minute if not
used, and it vanishes immediately if you use your hand
for some other purpose.
