Shielding Formation
You conjure magical shields of force to protect your allies around you. You and each ally who ends their turn within the emanation gain a +1 circumstance bonus to AC until they leave the emanation or the spell ends, whichever comes first. If an ally takes physical damage or damage from a spell or magical effect while being granted this bonus, they can choose to end the bonus for themselves as a free action to gain resistance 10 to all damage against the triggering damage. If they do, they become temporarily immune to the effects of shielding formation for 10 minutes. You can do the same by spending your reaction; if you do, you can't cast shielding formation again for 10 minutes, though you can continue Sustaining the benefits for others.

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.
Effects with this trait deal force damage or create objects made of pure magical force.
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.
