when i played this duo i doesn`t need or focus at summoning at all : carnage, frenzy, spamming autoattack like crazy and buff yourself from chants is all you need
And which buffing chants synergized particularly well with a barbarian in your opinion?
any what can increase your defences such as boost your deflection at chanter lvl 4 or that give you 10 fort and will from the start and there`s many more. with troubadour you can stack it through the fight and gave no problem to soak up damage.
