Grace of the King in Yellow

6th-level transmutation

Casting Time: 1 action

Range: 150 feet

Components: V, S, M (gold ingots worth 50 gp per 10 lbs. the target weighs, which the spell consumes)

Duration: Instantaneous

You target a humanoid you can see within range and suffuse its body with molten gold. The target must make a Constitution saving throw. On a success, the target weeps in the Mythos tears of molten gold and takes 5d6 fire damage. If collected, the golden tears are worth half the value of the material components for this spell. If the saving throw fails, the target’s bone marrow transforms into molten gold that expands and hardens into a golden replica of the target’s skeleton, shattering the bones. The shards of bone shred the creature’s insides and the molten heat sears its organs (although it doesn’t harm equipment). The victim takes 5d6 + 20 fire damage and 5d6 + 20 slashing damage. If this damage reduces the target to 0 hit points, its organs are ruined and it dies. It can’t be revived by raise dead.

A creature that survives this effect has its Strength and Wisdom scores each reduced by 1d6 + 4 from organ and bone damage. Magic that restores these ability scores ejects the golden replica of the victim’s skeleton from their body and deals 5d6 slashing damage. Resurrection and similar spells eject the golden skeleton harmlessly. This golden skeleton is worth the same amount as the material component of the spell.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 3d8 for each slot level above 6th. You can divide these dice as you wish between fire damage and slashing damage before rolling.
