Help making this a Power: SR Sterilize

[Kesendeja]

This spell allows a spellcaster to kill all bacteria (and other microorganisms) and destroy organic material such as skin flakes, stray hairs, and spilled blood. Material affected by this spell cannot be used as a material link. Because the spell does not affect biomaterial attached to a living being, it does not kill the various helpful and harmful microorganisms living inside a creature. Each hit scored by the caster inflicts a -1 dice pool modifier to any skill tests made to collect and use sterilized biomaterial for forensics or material link purposes. Shadowrunners often employ this spell to eliminate incriminating trace evidence, especially if blood has been spilled.

It's one of the last ones to do, and It's got me stumped. Any help is appreciated.

I can think of two ways to do it.
Innate Attack with a limitation only on organic residue and microorganisims.
I think -80% is fair and you only need 1 die of it I think.
Create with Destroy and a +50% Cosmic to affect complex things. Something similar was done in Pyramid to create plants.

The latter is more expensive and arguably less RAW but I feel more elegant.

Personally, I'd stat it as something like
Toxic Attack 1pt (Accessibility: Microorganisms and inanimate organic objects only -60%; Area Effect +50%) [1]
