You have been blessed with immeasurable power by the Lord of the Void. You are now completely unkillable, and immortal. You are immune to Cold, Poison, and Necrotic damage, but are severely damaged by Lightning. In addition, you gain mastery over lesser magic, causing spells of slot level three and below to no longer cost a spell slot. You may choose to expend the spell slot anyway, doubling the effects of the spell cast.

Taking this feat classifies you as an undead and gives you an innate spell focus. 

Primarily you appear as a skeletal figure drenched in dark mist, but you can veil yourself and make your outward appearance appear and feel exactly the same as your mortal form. 

You are able to summon weapons based on your current health percentage. Once you reach the respective threshold, you will no longer be able to summon the weapon. Only one instance of each weapon may exist in your care. Others may summon their own set, but may not use yours. You are always proficient with these weapons. All weapons cause fear on a failed WIS save.

>70% - summon the Judgement of Rev’ask. A massive polearm styled warblade seething in Voidic energies. 1d12+STR, lights target on fire for 1d4 turns.

>45% - summon the Fury of Rev’ask. A Void cloaked rapier like weapon that seems to swing faster with every successful strike. 1d10+STR/DEX, each successful hit grants +1 to accuracy roles.

>10% - summon the Pity of Rev’ask. An odd weapon that seemingly fires magical bolts from its dark barrel. 1d4+DEX, targets must make a saving throw based on the following d4 chart:

• 1 - target must make an INT save or be charmed.
• 2 - target must make a STR save or be knocked prone ten feet away.
• 3 - target must make a CON save or be poisoned.
• 4 - target must make a CHA save or be turned into a temporary ally under the control of the wielder.
