Using battle rage spends fury. The loss of damage comes from not being at max fury for a second or so. Switch out beserker rage to see for yourself.
To further elaborate, you're using Berserker rage. You need to be within 5-6 fury of your max for that to work. Using battle rage costs 20, and your BK weapons restore 10/sec. That's why it dips, goes back up after 1.5 seconds (15 fury regained), then dips a little again after 3 seconds (when taeguk falls off).
Yea just read your "Berserker Rage" passive brother
Its as Pleiszter said, spending fury makes it so you don't benefit from the passive Berserker Rage, untill you're close to full fury again.
My game is in polish, but everyone knows where is dmg when you open charcter.
So its little bug ? oj just some misscalculation ? or i'm missing some mechanic?
