Dude. Saying 'Artificer Badass' is like saying 'ATM Machine'.
Meanwhile, Paladins suck.
Why not crush him body, mind, and soul by kicking his ass with his own, so called Holy weapon? It's called Psychological Warfare. Gotta make him wonder if he really is on the right side eh?
It's still a +5 cold iron longsword (and could arguably be other weapon types, most DMs would allow it) that still gives SR of 5 + your level to you and any allies next to you, and still lets you do an area greater dispel at a CL = your class level at will once a round as a standard action. Besides, any half decent damage dealer doesn't need conditional 2d6 bonus damages anyways. They're using multipliers, or are Just That Badass.
