Ephemeral Tracking
You can look at currents in the air and water and see tracks that you can follow just as you would on land. You can use Survival to Track through both air and water, noticing aerial or aquatic "tracks" of all creatures who passed nearby in the last hour. It's more difficult to Track in this way: the DC to Track through air or water is always at least 30, or higher after precipitation or wind (in the air) or heavy tides or currents (in the water). It's possible to Cover Tracks against this spell, but creatures might not realize they need to do so.
Traits
An action with this trait requires a degree of mental concentration and discipline.
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.
