My Unholy Covenant VIII has the SAME EXACT stats as my Unholy Covenant VII at master lvl... This sounds like a bug to me, but what was the point of upgrading? UPDATE: Re-logging fixed it
The upgrade isn't huge but it's here. UC7 Master : 1170 Noxious, 704.5 power UC8 Master: 1338 Noxious, 787.4 power Or are you from Nagafen ? It seems quite a few spells are messed up in PvP atm.
Still, your question has merit. While the upgrade looks correct in theory (~12% increase) 80ish power in a 50K+ pool and less than 200 noxious are useless in practice.
