Solar

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

+1 Status to All Saves vs. Magic —

Regeneration 20 (Deactivated by Unholy) — This monster regains the listed number of Hit Points each round at the beginning of its turn. Its Dying condition never increases beyond Dying 3 as long as its regeneration is active. However, if it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn. Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4.

Aura of Protection (aura, divine) — 20 feet. Allies in the solar's aura gain a +2 status bonus to AC against evil creatures and a +2 status bonus to saves against effects from evil creatures. The bonus increases to +4 against control by evil creatures and attacks by evil summoned creatures. When the solar or an ally is hit by an attack from a creature in the aura, that foe must succeed at a DC 43 Will save or be blinded for 1 minute (this is an incapacitation effect). It's then temporarily immune for 1 minute.

Animate Weapon —

Arrow of Mortality — The solar doesn't need to provide ammunition for their bow. When they draw their bow, they create a magical arrow of light that sheds bright light in a 20-foot radius until the end of the solar's next turn.

On a critical hit with the arrow, if the target has 75 or fewer Hit Points after taking the damage, it drops to 0 Hit Points and becomes Dying 1 (or, if it was already dying, increases its dying value by 3).

Change Shape (concentrate, divine, polymorph) — The solar can take on the appearance of any Small or Medium humanoid. This doesn't change their Speed or Strikes.

The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

Holy Armaments (divine) — Any weapon gains the effect of a Holy property rune while a solar wields it.
