As a reaction, which you use when you are hit by an attack or missed by 4 or less, an invisible kinetic shield appears and protects you. Roll a d4 and add the result to your Defense until the start of your next turn, including against the triggering attack. You can do so after the roll but before any effects of the roll occur.

Additionally, you have advantage on saving throws to avoid being pushed until the start of your next turn.

Augment

Telekinetic Shelter. You can expend 2 additional mana to instead become enclosed in telekinetic energy as the damage against you is halved. For 1 minute/mana or until you end this feature on your turn, you have resistance to all damage as the field of telekinetic energy slows attacks and spells. The dome does not move with you.
