need a blood spike build

Yes i used the search engine and there's so many builds its hard to decide, If someone could post the stat points, and best skills for a blood spike, i would appreciate it.

Depends on where you are really, and what you need to do besides just spike damage. This is one I used for a good bit though:

Shadow Strike, Vampiric Gaze, Dark Pact, Awaken the Blood, Well of Power, +skills useful for where you are.

Basically you use shadow strike if they have >50% health, then alternate dark pact and vampiric gaze to recover your sacrificed health. Usually you will be able to do two dark pacts and then a gaze, and not end up with too much health lost from it, especially if you did Awaken and had 18 blood magic. After one enemy goes down, stand in the well of power to keep your energy and health up, the +2 energy regen will keep you casting continuously.

And when there are no corpses? Is sacrificing more health to get energy the best way?

When there are no corpses just use your soul reaping for energy, at level 10 you should be able to keep up a moderate casting rate, just not as fast as you could with the well of power.

If you really need to keep up constant casting, have another necro in the party use Blood Ritual, or if there aren't going to be any corpses at all switch out the Well of Power for Offering of Blood if you really need the energy.

dark pact is overkill u dont need it blood spike is slow enough if u cant get a person down by ss+gaze dont spike at all a good 3rd spike is barb signet only if u run under QZ its good to spike somoene down and save mana... try to have ur team hve about 9 soul reaping and MONK staffs then mix in prot + heals on ur necs.. skills are of ur choice be creative and u dont need awaken the blood btw
