cold users are hard to kill
for me [i had glaiver-force]
blader-cold was very hard to kill , but like a blader they have low phy attacks and need debuffs like bleed/div to kill, and because i was force they couldnt make on me debuff

but i have chance to kill them , as i know
decay lv 10 reduce 534phy def
phy buff+passive give you 336 phy def
534-336 = you still in -198 phy def.
and same with weaken down like 800mag fire buff 272
you are in like -528mag def [maybe not help alot to Str chars]
and Division raise your damage in 35-40%
and Impotent reduce opponent damage in 35-40%
Attack rating reduce - if you are bower its reduce your passive+bird
Parry ratio reduce - reduce over Light mastery lvl 80.
in force
you have
-selfcure every sec clean debuffs - not like purifaction pills 15sec delay
-selfheal every sec up over 5k hp [like two X large potions]
-debuffs - your main thing why you are force

-option , 3K mp increasing.
the dis adv in force
maybe low phy def - depends on your set
maybe low pr - depends on your set
no snow
no ice wall
maybe shit against holy word - disagree about this sight because Str-light or Str-cold cant debuff too [example as blader-cold - cant make debuffs too with his chains/smash , so its not so "disadvantange of force"]
