Well considering it's a caster helm, don't they kite non stop? So the physical damage they take is negligible to begin with
EDIT - Current bid as in it was an actual bid, or was that just the lowest that the seller had put it up for? to my knowledge you can't tell the difference
Kiting does not prevent physical damage by any stretch. Even with kiting, physical is probably the most valuable (fire might be slightly better due to mortar). Any elite's with Fast, or just mobs that are always fast are going to hit you no matter what you do. Anyways, the phys resist on that helm is just sprinkles, the -4 cost allows for amazing disintegrate spam (possible 0 cost with the right abilities set, I've tested it) and the int is one of the highest I've seen on a helm.
