[ ] Spirit of the Dragonslayer: Kessler's spirit patron, the Dragonslayer, can ASSUME DIRECT CONTROL for a scene. If someone willingly allows the Dragonslayer to possess them, they can gain spiritual armor (for some reason it looks quite like the primium plate armor of an Order of Reason crusader...), the Dragonslayer's Blade (deals aggravated unsoakable damage to supernaturals), and the Dragonslayer's spirit charms (which are great fun).

This is not actually a Shockwave code. However, the excuses you need to make are, in fact, roughly equivalent. Furthermore, the Dragonslayer will only ever show up to slay single powerful foes who hoard wealth and power.
