The Awakening

The Vampire can sense the remains of long-dead warriors and awaken then: to bolster his unholy ranks.
Whenever the Vampire casts the Necromantic spell Invocation of Nehek (see p. 58) he can add +D3 to the total number of Skeletons or Zombies created. For example, if he casts a Level 2 Invocation, he can raise 2D6+D3 Skeletons.
