Enervation Augmented (3rd): If you expend two uses of mythic power, any creature attempting to remove the target's negative levels must succeed at a caster level check (DC 10 + your caster level + your tier).

This spell does not remove negative levels that the subject has already gained, but it does remove the penalties from negative levels for the duration of its effect.
casted on itself (either by himself or by the Wizard he is hanging around with).
Does he or the wizard has to make a DC10+CL+Tier check, so is it possible the Enervation penetrated the Death Ward spell?
