question is: i have two Fel Relics 880 (+12% total on Demon Blades damage) but yesterday Krosus dropper 2 890 Fel Relics with shit traits (less magic damage taken i remeber)...can i use these last two relics 890 or 880 with good traits is better? At this moment i have 3 880 relic.
Got 875 Krosus relic yesterday and asked myself the same question because i have a 870 demon blades damage.
I simmed my char and Simc tells me it's a 3k dps increase to equip the 875.
If it's correct it should be an even bigger upgrade for you.
iirc demon blades deals roughly 5% or 6% of your damage while having 130% on demonblades (with 5 ranks in this trait).
So the trait increase is roughly 0.5% of your damage.
0.5% damage vs 4 weapon Ilvl, whatever the difference is, it is low, very low. I would use the higher ones.
