Solar

The solar knows if it hears a lie.

If the solar dies outside Mount Celestia, its body disappears, and it gains a new body instantly, reviving with all its Hit Points somewhere in Mount Celestia.

If the solar fails a saving throw, it can choose to succeed instead.

The solar has Advantage on saving throws against spells and other magical effects.

The solar casts one of the following spells, requiring no Material components and using Charisma as the spellcasting ability (spell save DC 25).

The solar makes two Flying Sword attacks. It can replace one attack with a use of Slaying Bow.

Melee or Ranged Weapon Attack: +15 to hit, reach 10 ft. or range 120 ft., one target. Hit: 22 (4d6 + 8) slashing damage plus 36 (8d8) radiant damage. Hit or Miss: The sword magically returns to the solar's hand or hovers within 5 feet of the solar immediately after a ranged attack.

Dexterity Saving Throw: DC 21, one creature the solar can see within 600 feet. Failure: If the target has 100 Hit Points or fewer, it dies. It otherwise takes 18 (4d8) piercing damage plus 36 (8d8) radiant damage. Success: Half damage.

The solar casts Cure Wounds (level 2 version), Lesser Restoration, or Remove Curse, using the same spellcasting ability as Spellcasting.
