Shields of the SpiritFocus 1
Source Pathfinder Player Core 2
Cast

Requirements You are wielding a shield.
You Raise your Shield, causing ephemeral spirit shields to float within your champion's aura. The shields last until the start of your next turn or until you're no longer raising your shield, whichever comes first. While one of your allies is in your champion's aura, the shields grant them a +1 status bonus to AC, and each time an enemy makes an attack against the ally, the enemy takes 1d4 spirit damage (even if it misses).
The benefit applies only while an ally is in your aura, ending for any ally that leaves and applying to any that enters later. As normal, you don't count as your own ally and therefore don't get the benefits of the spirit shields yourself.
Spell Effect: Shields of the Spirit
Heightened (+2) The damage increases by 1d4.

FocusFocus 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 Pointsโyou 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.
SanctifiedIf you are holy or unholy, your sanctified actions and spells gain the same trait.
SpiritEffects with this trait can affect creatures with spiritual essence and might deal spirit damage. A creature with this trait is defined by its spiritual essence. Spirit creatures often lack a material form.
