Solo Dervish + UW = Me Needing help!

Hello everyone i recently started using a build to solo the UW smites i have watched a couple of videos on it but still i either seem to die on the run or by the smites my build, weapon, armor is:
---Build----
Eremite's Attack
Sand Shard
Vow of Strength
Mirage Cloak
Mystic Regeneration
Intimidating Aura
Fleeting Stability
Physical Defense
P.S. i have tried other skills instead of physical defense using gwpvx to find alternatives but they also didnt work
---Attributes----
3 Inspiration Magic
9 Scythe Mastery
15 Earth Prayers
11 Mysticism
----Armor-----
Max Armor
5 Windwalker Insignia's
1 Superior Earth Prayers
1 Major Vigor Rune (not paying for a superior )
3 Rune of Vitae
----Weapon----
Droknar's Reaver
Stats
Damage = 15% (while health is above 50%)
Energy gain on hit:1
Energy regeneration -1
Enchantments last 20% longer

So at this point i have no idea what im doing wrong i do it normal mode and i have also tried the alcohol build and used alcohol but that didn't work very well either. So what is it that's making me do so poorly i do farm smites in the UW so i am familiar with UW run and everything so that's not it. Please help because i want to us my dervish to farm smites.

try this template, maybe don't use superior earth just to save on the health, i've been doing it just on 12 earth prayers stupidly but it works fine still.
use the same gear though, can farm the smites, coldfires and even the skeles. But you'll need a speed buff. i've been using cupcakes.
if you need a hand message me in game : God Gin Rai.

ok tried that build and used cupcakes and it worked my only problem is if their are 3 or more coldfire i cant kill them and how long does it take you to farm it? My first time took me a while i had to use 3 cupcakes but ill get faster at it the more times i do it.

you shouldn't even be wasting your time with coldfire nights they don't drop ectos

Oh lol I didn't know cold fires didn't drop ectos
