The Golden Rapier (5e Weapon)
From D&D Wiki
Weapon (rapier), legendary (requires attunement)
This ancient rapier was created by the first golden dragon, using his own scales as the material and forging the weapon with the magma of a volcano.
Scouring Flame. This rapier deals an additional 4d8 fire damage and leaves the target in a state of burning on a hit, dealing 1d4 fire damage at the end of each of their turns until they or a creature touching them ends this effect as an action.
Burning Sun. As a bonus action immediately after a hit with this rapier on your turn, you may force the target to attempt a DC 15 Strength saving throw. On a failure, their armor is destroyed as it is irreparably burned. This can not affect magic armor with a rarity of rare or higher, or adamantine armor. This may be used once, regaining use at dawn.
