You have reached the pinnacle of Necromancy and transformed yourself into a lich. Your obsession with disease and rot has affected your transformation: you bloat like a waterlogged corpse and your skin turns a sickly green. You gain the following benefits in addition to those of your ValdaSpire24 feature.
Gore Burst
When you drop to 0 Hit Points, your body explodes in a shower of necromantic energy.
Each creature you choose within 20 feet of you makes a Dexterity saving throw against your Necromancer spell save DC. On a failed save, a creature takes 5d10 Poison damage and 5d10 Necrotic damage and has the Poisoned condition until the start of your next turn. On a successful save, a creature takes half as much damage.
Master of Disease
When you deal 25 or more damage with ValdaSpire24, the target has the Poisoned condition and is cursed for 1 minute. Choose two of the following effects which afflict the target while it is cursed. At the end of each of its turns, the target can make a Constitution saving throw against your spell save DC, ending the curse and the Poisoned condition on a success.
Bleeding
Each time the target takes damage, it takes an extra 1d6 Necrotic damage
Disadvantage
Choose one ability. The target has Disadvantage on ability checks and saving throws made with that ability.
Garbled
The target can't speak coherently or cast spells with a Verbal component.
Red-Eye
The target has the Blinded condition beyond 10 feet.
Unsteady
The target has the Prone condition at the end of each of its turns.
