So I'm been thinking of doing a Stargate Roleplay using DFRPG, and for the most part I can run it out of the box with no trouble with only some minor reflavouring. The only snag I run into is this.

Zat'nik'tel. A.K.A Zats.

You knows, one shot stun, two shots kills, three shots Disintegrate.

I have no clue how to write it up gameplay wise. Any help on this would be greatly appreciated.
