Death Knight - Stage 3 (Soul Bind)

Boons:

• Soul Bind: Your transformation into an undeath has changed the magical nature of your body. You gain advantage on saving throws against spells and other magical effects. In addition, whenever you deal non-necrotic damage with a spell, you can choose to deal necrotic damage instead of the spell's normal damage.

Flaw:

• Existence of Death: Your body is a conduit for mass amounts of negative energies, which grants you increased power, but this does come with detriments. Upon taking damage from either a celestial creature, radiant damage, or a weapon that has been blessed, you take an additional 1d6 damage for each of your transformation levels.
