Attack Destroys Body if Fatal Enhancement?

[King_Of_Bel]

I am making an enemy in my campaign that is a sort of spirit vampire, it's energy drain ability is supposed to annihilate the enemy's body if the attack, an already heavily modified vampiric bite, is fatal, removing evidence and preventing resurrection. How should I price this enhancement? I was thinking a 50% cosmic enhancement for adding utility, but would a 100% modifier be more appropriate? Or is there a better way to go about this?

Affliction (Advantage: Rest In Pieces (Power-Ups 2: Perks); Link: Vampiric Bite), perhaps? Or Link a Cyclic 10d Toxic(?) Attack to the Vampiric Bite, with 10-20 cycles (enough to basically mutilate the average body to -10xHP)?

My instinct is the +100% lasting effect Cosmic.

If this is the only way you can destroy a corpse, I'd agree with a 100% Cosmic. If you can destroy any corpse (or even only people you personally had a hand in killing), that would be a Corrosive Aura, with an Accessibility limitation to only work on dead people.

Symptoms with Fragile (Brittle) and Fragile (Unnatural), which would represent permanent damage to the soul caused by the attack. After the target suffers a cumulative 1/3 HP from the attack, until they heal the damage caused by the attack, they are incapable of tolerating more than -(HP) damage without dying and their body falling apart after the death of their soul. Since their body automatically goes to -(10*HP) when they reach -(HP), they cannot benefit from resurrection because there is nothing left to resurrect.

In a setting where there is ressurection, that is an overly cheap way of preventing people taking advantage of it.

The standard seems to be treating disintegration type attacks as corrosion, though this isn't actually mentioned in the description of corrosive damage.
