Also, when using the Detect Weakness feature, the additional damage turns into radiant damage, and increases by a die step (1d4 becomes 1d6, 1d6 becomes 1d8, etc…) if the feature is used against undead.

Tales from the Crypt

At 6th level, you have advantage on saving throws against fear and resistance to necrotic damage.

Legend of the Shining Moon

At 13th level, you can cast moonbeam as a 4th level spell (your spellcasting ability for this spell is Intelligence).

The spell can be cast once, then you regain its use after you complete a short or long rest.

Morals of Death

At 18th level, you are protected against instant death effects and effects that instantly reduce your hit points to 0.  If you are affected by this type of effect, your hp are reduced to 1 instead. You also become immune to any effect that would reduce your maximum Hit Points.
