You have reached the pinnacle of Necromancy and transformed yourself into a lich. However, your lichdom has become corrupted by the all-consuming Dead Mists, leaving you as a gaseous, incorporeal wraith. You gain the following benefits in addition to those of your ValdaSpire24 feature.
Damage Resistance
You gain Resistance to Bludgeoning, Piercing, and Slashing damage.
Gaseous Body
Your lich form is gaseous and indistinct. You can enter and occupy the spaces of other creatures. Additionally, you can pass through small holes, narrow openings, and even mere cracks, though you treat liquids as though they were solid surfaces.
Fly Speed
You gain a Fly Speed equal to your Speed. You can't fall and remain hovering in the air even when you have the Incapacitated or Stunned conditions.
Master of the Mists
Once on each of your turns when you deal Necrotic damage to an enemy with your ValdaSpire24 or a Necromancer spell, you drain some of the target's life essence with the Dead Mists. You regain Hit Points equal to 2d6 + your Intelligence modifier, up to a maximum of the Necrotic damage dealt.
