Messenger of the Cosmic Gods [Heroic Feat]

READ THIS: This is a Heroic Feat. It cannot be taken normally with an ASI or chosen at 1st level by any race. Instead, any character can take it instead of their class' level 20 capstone ability.

You have earned yourself the direct friendship of an all-powerful deity, which gazes at you from the sky and helps you with your every move. You gain the following bonuses:

• You gain resistance to necrotic and radiant damage.
• You learn two spells of 3rd level or lower from the cleric or druid spell list. You can cast each of them at 3rd level once per long rest. You can choose Wisdom or Charisma to be your spellcasting ability for those spells.
• The first time each day you fail a death saving throw, you critically succeed it instead and are brought back to consciousness with 1 hit point.
