Invocation Type: Lesser; Eldritch Essence
Spell Level Equivalent: 4
This eldritch essence invocation allows you to change your eldritch blast into a hellrime blast. A hellrime blast deals cold damage. Any creature struck by the attack must make a Fortitude save or take a -4 penalty to Dexterity for 10 minutes. The Dexterity penalties from multiple hellrime blasts do not stack.
If used with a Blast Shape that normally requires a reflex save (such as Eldritch Doom, or Burst), the hellrime blast will instead require a fortitude save.
