SFS Standard Twisted Dark Zone [one-action] Feat 10

Source Player Core pg. 172
You expose this reality to a realm of pure darkness filled with gibbering voices and otherworldly entities. The area of your quantum field functions as though it were an area of 2nd rank darkness. Creatures that begin their turn in the area must succeed at a Will save against your class DC or become confused for 1 round. Creatures that critically succeed are then immune for 24 hours. If this darkness is successfully counteracted, the quantum field’s other effects remain

Traits

Anchoring:You can use abilities with the anchoring trait only while your quantum field is activated. If you use the ability on your turn, in addition to their stated effects, they automatically Sustain your quantum field.
Darkness: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 it, but some darkness spells automatically attempt to counteract light.
Zone:These actions apply an additional effect to your quantum field. You can apply the effects of a zone only to a quantum field that doesn't have a zone effect.
