Questions About Hemalurgic Spike

Hemalurgic Spike launches a bloodspike from your outstretched hand to damage your opponent, absorb some of their health, and possibly absorb a skill or an ability for a short time.  This Destruction spell can "spike" mortal NPC races, as well as Falmer and Dremora, to absorb skills or abilities.  Foes have these abilities stolen from them and they are then applied to you and last for 15 minutes (5 hours in game).

This spell is available to Nightstalker Vampires or higher, and will always cause damage to an opponent (50-90 depending on your Vampiric rank).
You can always absorb health (10-20) if your victim is not a Dwarven automaton.
You can always replenish some Blood Points (10-20) if your victim is not a Dwarven automaton (if Blood Points are enabled).

You can only "spike" an individual once.  If you "spike" another NPC, and hemalurgy absorbs their skill/ability, it will overwrite any previous effects you had.
