in my opinion, with the introduction of "Old" Uniques...
BASIC pk gear should be the following for mages:
2x OLD SSE
OLD Skeleton Belt
Old imir,flame, shios
Old Elemental Pendant
DD15 or DD25 helmet
mage earrings are just garbage, im not sure i would ever buy a pair...theyre only half decent at +4 or +5 haha
harpy belts are also not very good...unless youre trying to go ghetto and go for a "iron belt" by swapping out between an old skeleton belt and belt of harpy
priest pendants do nothing for mages except maybe getting them killed.
get rid of it
