COH or Treachery for merc find items barb travi

Hi, if look for maximum damage merc, for fast run kill
hero have teleport
no cold damage for skill find items barbarian
play only Travincial

=my equip now,
Merc 2act nightmare offensive
Guillaume + shael rune
Highlord
Treachery
BK5
Trang belt
Laying of Hands
Gore Rider + UP
Infinity in regular tresher with good ed
\ frame: 60 fhr, 75 ias

if i change:
Trang belt to Nosferatu
Treachery to COH
\ frame: 42 fhr, 42 ias, but take bonus from COH

what better?

 

I would prefer treachery because of the attack speed it gives is massive amount and should be considered wearing it+ fade proc as well lvl15.and dont change the belt its fine for cannont be froZen effect.

 

I m using treachery(best choice in my opinion),and rising sun amylet(vs hydras,they will heal your merc),and you can use reapers tool(decrepify curse)

 

why people not read what write in 1st message
1) rising bad for damage and merc have bo and life\lich
2) reaper take cold damage and some corpse out

 

Why not fortitude?
+300% Enhanced Damage

 

20% Chance To Cast Level 15 Chilling Armor when Struck
and some corpse can go out too

 

Oh,I was careless about "cold dmg", anyway treachery beats Coh

 

but is minimal, i prefer forty, because u get fast kills and these "corpses out" is recovery on time. and... i recommend switch that belt trang to nosferatu (more ias and life leach) and ring bk for raven have more ar and no frozen. i prefer more AR than 1 skill on merk. Just a opinion..

 

Ravenfrost has cold damage which can shatter foes mostly.

 

i'm using now a life leach ring in.. is better
