Vampiric Touch is an ability in the Shadow tree for priests. This ability has large raid viability as it acts like a mana battery. Puting a Shadow priest in a healing group or a group that uses mana to dps in raids, such as a group with mages and warlocks, is very effective at easing the burden of mana on a raid.

Tips and tactics

The long term mana cost of this spell, assuming that it lasts its full duration, can be calculated by

 NetManaCost = BaseManaCost - (BaseDamage + ShadowSpellDamage)*TalentBonuses*.05

where

• NetManaCost - total mana cost after the return from the spell's damage
• BaseManaCost - initial mana cost as noted above
• BaseDamage - base damage as noted above
• ShadowSpellDamage - bonus shadow spell damage
• TalentBonuses - additional damage coefficients from [Darkness] (1.1), Misery (1.05), [Shadow Weaving] (up to 1.1), and [Shadowform] (1.15),

for a possible total of ~1.46. These coefficients stack multiplicatively.

The following table lists the bonus shadow damage required to nullify the mana cost of various spells at their highest rank while Vampiric Touch is active on the target. The damage required from the spell in order to do so would be equal to 20 times its mana cost. All values rounded to the nearest tenth.

Spell	Mana Cost	Required Shadow Damage in [Shadowform](+15%) only	In addition to Misery(+5%) and [Darkness](+10%)	In addition to full [Shadow Weaving](+10%) debuff
