Metamorph.

Your brain allows you to alter a creature's body chemistry, letting you close wounds, grant superpowers, and even bring back the dead with a mere touch of the mind. Metamorphs are sometimes called changers.

Level 2 Features:

Metamorphosis Adept.

When you roll a manifestation die to learn a new metamorphosis power, you can roll the die twice and use either roll.
In addition, after you make a manifestation test to manifest a metamorphosis power, you can reroll the manifestation die and use either roll. You can reroll a number of manifestation tests equal to your Intelligence modifier (minimum one test), regaining all uses when you finish a long rest. You can use this feature only once for a single manifestation test.

Psionic Toughness.

Your touch enhances a creature's toughness. As an action, you touch one creature (which can be yourself) and confer the following benefits to them for 1 hour:
-The creature's hit point maximum and current hit points increase by a number equal to your Intelligence modifier + your talent level (minimum 1).
-The creature has advantage on death saving throws.
You can use this feature a number of times equal to your Intelligence modifier (minimum once), regaining all uses when you finish a long rest.

Level 6 Feature:

Mind Surgeon.

By force of will alone, you close a creature's wounds or cure what ails them. As an action, you touch one creature (which can be yourself) and gain strain up to your proficiency bonus. For each strain you gain this way, the target regains 1d10 hit points, or you cure the target of one disease or neutralize one poison affecting them.

Super Senses.

The psionic power flowing through your body heightens your senses. You add a bonus equal to your Intelligence modifier to Wisdom (Perception) checks and to your passive Wisdom (Perception) score.

Level 10 Feature:

Death Foiled.

By expending psionic energy, you return a dead creature to life. After spending 1 hour concentrating on and touching the remains of a creature that died within the last 8 hours, you gain 8 strain, and the creature returns to life with 1 hit point. Any poisons or diseases that affected the creature when they died are neutralized or cured when they return to life. This power closes all mortal wounds and restores any missing body parts.
Additionally, if you die and can gain 8 strain without surpassing your strain maximum, you gain 8 strain and your remains reform 1 hour after your death. When your remains reform, you return to life as above.
You can use this feature to return a creature to life (including yourself) once, regaining the ability to do so when you finish a long rest.

Level 14 Feature:

Psionic Evolution.

Any creature that benefits from your Psionic Toughness feature gains the following additional benefits for 1 hour:
-The creature is immune to disease, poison damage, and the poisoned condition.
-The creature's speed increases by 10 feet.
-Once on each of the creature's turns when they deal damage to a target with an attack, power, or spell, they can deal extra psychic damage to the target equal to your Intelligence modifier (minimum 1 damage).
