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.

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.

Effects that slightly alter a creature's form have the morph trait. Any Strikes specifically granted by a morph effect are magical. You can be affected by multiple morph spells at once, but if you morph the same body part more than once, the second morph effect attempts to counteract the first (in the same manner as two polymorph effects, described in that trait). Your morph effects might also end if you are polymorphed and the polymorph effect invalidates or overrides your morph effect. The GM determines which morph effects can be used together and which can't.

This indicates abilities from the sorcerer class.
