Usage
Warning: Due to an update when Factions was released, Blood of the Master now heals all allied minions. If you have at least 5 Minion Masters in the party, you can actually kill yourself using this skill.

The sacrifice works like so:

If you keep this progression up, 4 minion masters with 10 minions each tied to them is an 85% sacrifice. With 5 or more minion masters controlling 48 minions between them, this skill will sacrifice 101%; in effect killing your character outright regardless of your points in Death Magic.

The use of Aura of the Lich helps to counter the sacrifice costs. A swarm of 4-5 Vampiric Horrors is usually enough to counter all sacrifice costs for about 10 Minions altogether, while spamming Blood of the Master.
