Divine Crucifixion

A faint golden glow emanates from your hand, giving you the power to crucify even a god with just a single touch.

Make a melee spell attack against one creature within reach. On a hit, the target is lifted up into the sky with their arms bound to an upwards facing golden arc and held there for 2 turns. On the target’s next turn, they must make a DC 30 Constitution saving throw or take 100d6 radiant damage, half as much on a successful save, as an impossible amount of golden shards pierce every location on the creature’s body. On their second turn, they must make a DC 30 Constitution saving throw or take 6d100 radiant damage, half as much on a successful save, as all of the shards explode. 

This attack ignores immunity to radiant damage and instead treats immunity as resistance.

If concentration is broken, the target is released from their crucifixion. If the target survives, they are released from their crucifixion but also have a -5 to all ability scores, if they failed both Constitution throws it increases to -10. If this reduces one of their ability scores to 0, they will die as liquid gold pours from their facial orifices.
