(material, somatic, verbal)
Area 20-foot burst
Range 120 feet
Duration 1 minute

You create a shroud of magical darkness that feeds on those inside it. This globe of pure darkness is identical to that created by a 4th-level Darkness spell. Blunt, gnashing teeth made of shadows gnaw at the creatures within. Make a spell attack roll against the Fortitude DC of each creature in the area. Any creature that fails takes 4d6 bludgeoning damage as teeth attach to it. While the teeth are attached, it takes a –10-foot circumstance penalty to its Speeds and can't Step. Whenever a creature ends its turn in the area, the teeth attempt to attach to that creature if they haven't already, and they deal 1d6 bludgeoning damage to any creature they're already attached to. The shadowy teeth become unattached from any creature that leaves the area but can't otherwise be detached from a creature while that creature remains in the area. You can Dismiss the spell.

Traits

Uncommon

Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.

Necromancy

Effects and magic items with this trait are associated with the necromancy school of magic, typically involving forces of life and death.

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 the light, but some darkness spells automatically attempt to counteract light.
