Barbarian C3 seems bug. To cut it short, here’s what I found:
My Frenzy skill is on lvl. 10. The damage stack should reach x20 according to the description. But on the tooltip, it stops on x10.
I just learned the class skill of Barbarian which increases Barbarian debuff duration by 1 second per attribute level. It’s level 10 now, but my Cleave debuff duration is still 5 seconds while the enemy is debuffed with Warcry. I tried stun too, but still no.
There are no bugs related to those abilities:
Check your attributes, if you have Frenzy: Maintain Stacks active (https://tos.neet.tv/attributes/105012) your stack won’t go past half of your max stacks, but you won’t lose them when switching target: if you want to have 20 stacks at level 10, you need to toggle the attribute off, but you will lose stacks when changing target, that’s how the skill works.
If you’re talking about Warcry: Debuff Duration (https://tos.neet.tv/attributes/105021) well, you need to use Warcry on your debuffs, to extend them… First you use the debuff (Cleave, Stun) then you use Warcry to extend their duration!
Both works just fine. 
oh. thanks man. it seems i havent read the Frenzy maintain stacks description word by word. lol
As for the debuff duration, Im pretty sure i tried it also earlier. Debuff thrn Warcy. Duration didnt increase. but I will try again later. I think its maintenace now.
Thanks sir
You’re welcome!
If it still doesn’t work, it may be related to this nice bug we currently have which doesn’t load our characters attributes properly on certain field maps/cities… it’s been here for a week or two, I can’t remember exactly… still, this affects everyone tho, it can’t be helped, we are all still waiting for it to be fixed.
