Gain resistance to all magic damage, and advantage on saving throws against spells and magic effects. Your body is made out of condensed ather energy instead of normal flesh.

As a bonus action, you can summon a sword made out of pure ather energy. Deals 1d8 + STR/DEX force damage, and counts as a magical weapon. It cannot be disarmed, and leaves Leaves faint silver ather‑residue when striking.

Balance Cut (1/rest): On hit, end one magical effect on the target (Con save)

Because of your lack of a solid physical form, you have a weakness to non-magical bludgeoning damage, and critical hits deal 1 extra die of damage. On taking a critical hit, roll a con save of 10 or half of the damage taken (whatever is higher) or lose concentration on your current spells. Also when hit, your form "glitches" in a grey-whiteish color.

When taking force damage, roll a D20. If a 1-5 was rolled, an echo of yourself appears randomly on the battlefield. The echo acts on 0 initiative, and makes a melee (1d6 force) attack against the closest target to it within a 5ft radius, then disappears.

You do not bleed normally, instead, you bleed drops of a silver-like substance. When emotional or casting spells,  your body flickers or "glitches" in a silver-gray color.

When casting spells, they will usually come out a silver-gray color, as well as manifesting in geometric patterns; especially force-based spells. Illusory spells can be used to conseal the flickering and "glitching" of your form.

As an Ather-Born Human, you gain +2 to intelligence, and +1 to constitution or +1 to strength.
