Death Ward

You touch a creature and grant it a measure
of protection from death.
The first time the target would drop to 0 hit
points as a result of taking damage, the target
instead drops to 1 hit point, and the spell ends.
If the spell is still in effect when the target is subjected to an effect that would kill it instantaneously without dealing damage,
that effect is instead negated against the target,
and the spell ends.
