Mystery ancestors

Cast [>>] somatic, verbal

Duration sustained up to 1 minute

You take the form of your ancestral spirits, becoming invisible and quasi-corporeal. You gain resistance 10 to all damage (except force and damage from Strikes with the ghost touch property rune), and this resistance is doubled against non-magical and precision damage. You gain a fly Speed equal to your land Speed; when Flying, moving upward isn't difficult terrain for you. You can't move through solid objects, but you can float through tiny gaps. You can't Cast Spells (but you can Sustain a Spell), activate items, or use actions that have the attack or manipulate trait.

Heightened (+2) The resistance increases by 5.
