Spell Desicate the supernatural

[Dead Horse]

Can someone confirm or explain this spell to me?

My players are sayings a save or die spell, killing the supernatural creature in a matter of seconds if save is failed. If save is made it does an incredible amount of damage.

Are we reading the spell wrong?

[Glistam]

Yes. It does full damage if the save is failed, and it does half damage if the save is passed. It only instantly kills the creature if it does more damage than the creature has in M.D.C..

I'm going to slightly disagree with Glitstam.
-- Failed save = full damage; only lethal if the damage is high enough for that target.
-- Successful save = no damage. (I don't see any mention of half-damage in the spell.)

The last line of the spell in RBoM 1st printing says that a successful save means only half damage.

Thank you. I completely missed that last line, and stand corrected.
