Azareck's Ruthless Laceration

Release a beam of necrotic energy that lacerates and mutilates the body of your target.

The target must make a Constitution saving throw or take 10d6+40 Magical Slashing damage. If the target is reduced to 0 hit points from this they are turned to a black sludge and they can only be resurrected via True Resurrection or Wish. Undead and Constructs are immune to this part of the spell.

If the creature has blood, for the next 1d4+1 turns they must make a Constitution saving throw at the beginning of their turn. If they pass nothing happens, on a fail they take 2d4 necrotic damage as they bleed out from their wounds.

At Higher Levels: When you cast this spell with a spell sloth of 7th level or higher, the initial damage increases by 1d6 for each slot above 6th. For every 2 levels above 6th the bleed damage increases by 1d4.
