Trigger A creature damages you.
You curse the target with your outrage at being attacked. The effect is determined by the target's Will save.
Critical Success The target is unaffected.
Success The target can't Observe you until the end of its turn, and if you're currently observed by it, you become Hidden to it.
Failure As success, and for 1 minute, every time the target damages you, it can't observe you until the end of its turn.
Critical Failure As success, and for an unlimited duration, the first time each round the target damages a creature, it can't observe that creature until the end of its turn. If it damages several creatures at once, the creature it can't perceive is chosen randomly among those creatures.
Traits
An action with this trait requires a degree of mental concentration and discipline.
A curse is an effect that places some long-term affliction on a creature. Curses are always magical and are typically the result of a spell or trap. Effects with this trait can be removed only by effects that specifically target curses.
This effect alters a creature's emotions. Effects with this trait always have the mental trait as well. Creatures with special training or that have mechanical or artificial intelligence are immune to emotion effects.
An ability with this trait can take a character completely out of the fight or even kill them, and it's harder to use on a more powerful character. If a spell has the incapacitation trait, any creature of more than twice the spell's rank treats the result of their check to prevent being incapacitated by the spell as one degree of success better, or the result of any check the spellcaster made to incapacitate them as one degree of success worse. If any other effect has the incapacitation trait, a creature of higher level than the item, creature, or hazard generating the effect gains the same benefits.
A mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
