Dim the Light
Trigger You cast a darkness or shadow spell.
You magnify the darkness from the triggering effect, causing the ambient light level to flicker briefly so you can slip from sight. You can immediately attempt a Stealth check to Hide, and you can become Hidden to a creature even if you don't have cover and aren't otherwise concealed from that creature. You cease being hidden at the end of your turn unless you move into cover or become Concealed before then.
Traits
Darkness effects extinguish non-magical light in the area, and can counteract less powerful magical light. You must usually target light magic with your darkness magic directly to counteract the light, but some darkness spells automatically attempt to counteract light.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
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.
