Eldritch Truth
Wizard
Level 3: Eldritch Power
Secrets of eldritch magic hidden within your spellbook grant you additional powers.
Mental Resistance.You have Resistance to Psychic damage.
Fractured Mind. Whenever you finish a Long Rest, you can access your Eldritch Spellbook, a fragment of your mind that exists beyond physical reality. When you inscribe a spell into your physical spellbook, you can also record it within your Eldritch Spellbook at no additional cost. While accessing your Eldritch Spellbook, you can copy spells contained within it into your physical spellbook without spending gold.
Eldritch Familiar. The Find Familiar spell appears in your spellbook and doesn't count against the number of Wizard spells recorded there. When you cast Find Familiar, you can change the familiar's creature type to Aberration.
Level 6: Profane Ritual
When you finish casting the ritual version of a Wizard spell, you can grant yourself Temporary Hit Points equal to your Wizard level plus the spell's level. When you complete a ritual in this way, the area immediately surrounding you becomes noticeably withered and warped. Plants wilt, insects perish, and delicate life visibly twist as the ritual affects the environment.
Level 10: Mirror Mind
When a creature targets you with a spell or magical effect that requires you to make an Intelligence, Wisdom, or Charisma saving throw, you can force that creature to make the same type of saving throw against your Wizard spell save DC. On a failed save, the creature perceives a psychic echo of you until the end of its next turn. While affected by this psychic echo, whenever the creature makes an attack roll or a saving throw, it must subtract 1d4 from the roll.
Once you use this feature, you can't use it again until you finish a Short or Long Rest.
Level 14: Forbidden Revelation
The death of lesser minds grants you fleeting glimpses into truths mortals were never meant to comprehend.
When you kill a creature with a Wizard spell of 1st level or higher, you can use your Reaction to regain one expended spell slot. The recovered spell slot must be at least one level lower than the spell used to kill the creature, and it can't be higher than 5th level.
You can use this feature a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses when you finish a Long Rest.
