Buff Pegasus

Celestial Resistance. You have resistance to necrotic and radiant damage.

Elemental Resistance. You have resistance to fire damage.

Holy Light. The Sword of Zariel sheds bright light in a 5-foot radius and dim light for an additional 5 feet. Fiends find the sword's light disconcerting and painful, even if they can't see it, and have disadvantage on attack rolls made within the weapon's radius of bright light.

Sword of Zariel. Melee Weapon Attack: +12 to hit, reach 5ft, one target. Hit: (1d8 +10) slashing damage plus (2d8) radiant damage. An evil creature that takes this radiant damage must succeed on a DC 17 Constitution saving throw or be blinded until the end of its next turn.

Shoulder Charge. Melee Weapon Attack: If Buff Pegasus moves at least 10 feet straight toward a target and uses this attack, the target must succeed a DC 20 strength saving throw or take (2d6 + 10) bludgeoning damage, and gets pushed back 10ft. On a successful save, the target takes half the damage, and does not get pushed back 10ft.

Heavy Kick. Melee Weapon Attack:  +7 to hit, reach 5ft, one target. Hit: (5d6 + 10) bludgeoning damage.

Intensify Glow. As a bonus action, you can intensify the sword's light, causing it to shed bright light in a 15-foot radius and dim light for an additional 15 feet, or reduce its glow to its normal intensity.
