From the doing the path of Arah sPVP reward track I got a couple of Arah exotic weapons that have a Major Sigil of Undead Slaying (+5% dmg vs undead, 2% dmg).
When doing the Arah dungeon should I switch to these weapons? Are they worth it? My regular weapons are also exotic but with +7% crit chance and +stats (pow, pre, vit) runes/sigils. I'm a thief.
Otherwise I'll just disenchant these... Or should I collect multiple weapons set with the different sigils?
