设定场景如下
13级或更高等级的duskblade在一次全回合攻击中引导了吸血鬼之触并攻击了四个敌人(加速术或旋风攻击)，四次攻击分别造成了 182 180 185 296(重击，杀死该敌人，其hp为280)伤害。此次攻击获得的临时hp该如何计算？因为引导的一直是同一个吸血鬼之触（参见下面的规则原文），我个人理解可以将所有造成的有效伤害合计来计算所获得的hp(837临时生命)，还是只取最大的一次伤害计算(290临时生命)？
吸血鬼之触法术详述
Vampiric Touch
Necromancy
Level: Sor/Wiz 3
Components: V, S
Casting Time: 1 standard action
Range: Touch
Target: Living creature touched
Duration: Instantaneous/1 hour; see text
Saving Throw: None
Spell Resistance: Yes
You must succeed on a melee touch attack. Your touch deals 1d6 points of damage per two caster levels (maximum 10d6). You gain temporary hit points equal to the damage you deal. However, you can’t gain more than the subject’s current hit points +10, which is enough to kill the subject. The temporary hit points disappear 1 hour later.
Duskblade职业描述中关于全回合攻击中奥术引导的部分
At 13th level, you can cast any touch spell you know as part of a full attack action, and the spell affects each target you hit in melee combat that round. Doing so discharges the spell at the end of the round, in the case of a touch spell that would otherwise last longer than 1 round.

At 13th level, the duskblade’s arcane channeling class feature (PH2 20) says “you can cast any touch spell you know as part of a full attack action, and the spell affects each target you hit in melee combat that round.” If you hit the same creature more than once during the full attack action, does the spell affect it each time you hit?
No. The spell affects each target only once.
If a rogue delivered a sneak attack with the vampiric touch spell, would the extra damage from the sneak attack also give her extra hit points? And could the sneak attack dice allow her to exceed the maximum damage allowed by the spell?
Yes and yes. The spell simply says that you “gain temporary hit points equal to the damage you deal.” The spell doesn’t seem to care how you get to that value (Empower Spell, sneak attack, and so on), so a rogue who delivered 50 points of damage with vampiric touch would gain 50 temporary hit points. The maximum damage listed for the spell only applies to the damage gained by your caster level; it doesn’t take into account any other benefits the character might have, such as sneak attack damage.
