this is the fulminator i got. rerolled the 700vit to 700+ dex. was gonna make it socket but out of breath and souls.
so a soc is still more worth than 700+ dex?

what can I do to improve again?

feel like getting rid of my ring, pants and shoes.

how about showing me your profile so I can have some idea on what item should i get? 

Since when did vit gives dps. You sure you got the facts right?
Whats your AR at currently? Im at about 1.3k buff. You still can upgrade your ammy, glove, ring. Trifecta will help to boost your dps.

As for your the Barber dagger, try get above 2k dps. That will also help you.

For AR you can try to focus on one resistance to maximize OWE.

Oh, next time state la the passive.... I was wondering since when vit directly turns into dps.. But why waste a passive slot? That passive needs heal or shield spell to activate that extra damage right? Since it only last 10 seconds, its not consistent dps.

wat means shield always up?

Thanks

Oh, here is a video doing solo in T2. Crit from normal attack (Crippling Wave) is around 2.5mil. The last part, Champion was killed in 6 seconds (that is a weak champion anyway hehe)

DPS: 700k
Toughness: 6.5mil
