You tell a magical joke and infect a target with laughter that spreads to those nearby. The first time you Sustain the Spell each round, you can target another creature you can see that is within 30 feet of an affected target. The new target need not be able to see or hear the affected target, as the humor spreads magically. You can't target the same creature more than once with this spell.
Critical Success The target is unaffected.
Success The target begins giggling and can't use reactions.
Failure The target is Slowed 1 and can't use reactions.
Critical Failure The target falls Prone and can't use actions or reactions for 1 round. It then suffers the failure effect.
Traits
An action with this trait requires a degree of mental concentration and discipline.
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.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
A mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
