"Blood Necro" usually includes a variety of skills, and can include:
- either Blood Ritual (a.k.a. BR, at one time was also called Rit but changed for obvious reasons) or Blood is Power (BiP, Prophecies-only Elite) to give Energy to the casters, especially healers. The advantage of BiP is that it's a lower energy cost and you do not have to touch the person to give energy, so you can save being drawn into battle or distracted too far... but you sacrifice more health.
- Well of Blood (WoB) or Well of Power (Prophecies-only Elite, a.k.a. WP, since WoP is filtered in the game) as an effective support heal -- WP also helps regen Energy.
- degen skills such as Life Siphon / Transfer, Barbed Signet, Dark Pact, Unholy Feast, Vampiric Gaze, etc.
- sometimes Orders skills, such as Order of Pain (OoP) or Order of the Vampire (OotV) which are effective team support skills, but should have some health regen to balance the sacrificing. Orders Necros can be a whole specific build, and can sometimes get into the Curses-based Order of Apostasy, for those depending on Canthan Elites.
SS = Spiteful Spirit (Prophecies-only Elite), a Curses skill, and as mentioned is usually linked with Spinal Shivers or Shivers of Dread. Regardless of Sympathetic Visage, Shivers skills are usually abbreviated as Sv.
And for those of you who are Cantha Necros, don't fret over all the Prophecies-only Elites: people just haven't figured out the effectiveness of the Canthan ones yet (i.e. Wail of Doom).
