Diminution

Immortal Discipline

You manipulate the matter that composes your body, drastically reducing your size without surrendering any of your might.

Psychic Focus. While focused on this discipline, you have advantage on Dexterity (Stealth) checks.

Miniature Form (2 psi; concentration, 10 min.). As a bonus action, you become Tiny until your concentration ends. While this size, you gain a +5 bonus to Dexterity (Stealth) checks and can move through gaps up to 6 inches across without squeezing.

Toppling Shift (2 psi). As a bonus action, you shift to an incredibly small size and then suddenly return to normal, sending an opponent flying backward. Choose one creature you can see within 5 feet of you. It must succeed on a Strength saving throw or be knocked prone.

Sudden Shift (5 psi). As a reaction when you are hit by an attack, you shift down to minute size to avoid the attack. The attack misses, and you move up to 5 feet without provoking opportunity attacks before returning to normal size.

Microscopic Form (7 psi; concentration, 10 min.). As a bonus action, you become smaller than Tiny until your concentration ends. While this size, you gain a +10 bonus to Dexterity (Stealth) checks and a +5 bonus to AC, you can move through gaps up to 1 inch across without squeezing, and you can’t make weapon attacks.
