You see with my setup the dps decreases to 6072,11 almost same with what you have with several gear pieces different. BUT i kept drinking time "0".
If you type 300 for drinking time, then i see the new dps value as: 6204,80
I hope u can check again. Thanks in advance.
I've downloaded this file and opening it shows DPS at 5876.77. If I change drinking time to 300, DPS is at 5997.98. Again, just as Kavan said, I don't know why you have drinking time set to 0. It's starting you at 0 mana for the fight. That can't possibly make any sense to you.
Even so, 5997.98 DPS (version 2.1.6) is still less than the 6072.51 I've posted. You still have some problems in your set though. First, you have too much hit. It's a small DPS increase to switch the veiled to a reckless in the robes. Next, there's no reason to use the Runed Dragon's Eye in your gloves. It's another DPS increase to switch the Dragon's Eye to a Runed Scarlet Ruby, and replace the Reckless gem in your robes with the Dragon's Eye. We're now at 6003.87.
Next we'll switch out the Rigid Dragon's Eye, a loss of 54 hit, and replace them with Runed, for a gain of 64 spell damage. This drops DPS considerably (5977.91).
To make up for this, we're dropping the Unsullied Cuffs for Bindings of the Expansive Mind (-42 useless spirit, -34 haste, -18 spell power, +43 crit, +28 hit). This puts our DPS at 6020.40. We're still 52.11 behind though. You have two stats holding you back: spirit on your helm and spirit on your chestpiece. One of these has to go. Replacing your robes with Heigan's Putrid Vestments (Runed Dragon's Eye and Reckless gem) puts DPS at 6021.66. It's a small DPS upgrade because we've lost the 4-piece set bonus.
To get this back, we equip Valorous Frostfire leggings with 1 Runed and 1 Veiled. This puts us at 6041.75. Equipping Leash of Heedless Magic drops us to 5978.12, but replacing Embrace with Dying Curse puts us at 6061.47. Change the Veiled in the leggings to a Reckless and you end up at 6072.51.
