If a unique or a runeword can take that spot and do better, then the rare won't do justice.
Most of the time, shine more during low / mid level dueling due to the restriction.

desirable on the sorc clasped orbs or necro off hands or if those items aren’t used for pvp
Non-pvp desired skills?
Title says "dueling"
For sorceress, teleport (saving skill points from investing into the skill branch), Main/sub-dps skill, warmth, one of the 3 cold armors, one of the 3 element masteries.
At the very least, it would require +2 sorceress, main/sub-dps along with element mastery (since level requirement does not matter much and you want the best of the best for pvm).
Open sockets and the other described skills. (it has to outshine in terms of damage when compared to uniques / runewords).
Follow up with the usual rare orb stats that can be found on it (health / mana / life rep / resistance).
As for Necro shields, its the usual suspects for pvm.
Summons would be the best thing to look for.
Skeleton mastery / revive / any 'summons' / corpse explosion
