I agree with berserk build and some FCR, however there are some strategies that have been left out, for example, if one of the council members has Conviction aura, you have less resistence, so you want to kill of that member first... you need to tele stomp the conviction one as soon as possible, and you also have to ensure you have stacked Fire res since they all use fire skills.
Oh, another point, horck bodies before leaving the area by way of Town portal or using the stairs to level one(1) ... note, this is a good way to escape a barrage of hydras.
Ismail Vilehand and Toorc Icefist are casting hydra lvl 9
Geleb Flamefinger is casting hydra lvl 10
All 3 of them have a bonus of +100% fire skill dmg
This make their hydra dmg respectively 120-147 and 135-164
Hydras are coded as 'pet'.
When a pet attacks a player, its dmg is modified by the same as pvp penalty, multiplied by 0.17
So if we look at the highest possible dmg from the max value of 1 bolt from lvl 10,
164*0.17 = 27.88 (rounded up to 28)
Then MDR is calculated before resist.
You get 30 mdr from 2x dwarf
28 - 30 = zero dmg left
Even if you are down to -100 res because of conv... 0 multiplied by 2 is still zero.
So it's the opposite of what you said.
If there is one aura you can target last, it's conv, because all other auras are more dangerous. But in reality it's extremely irrelevant... just kill whatever is in front of you, don't waste time chasing a particular member.
You need light/cold res. They deal a lot of it on attack, they're often light/cold enchanted, and also the Hierophants around are casting blizzard and lightning.
Howl is a skill for a berserker to use, now it only works on lower minion, not champions... Anyway, if you build this character class properly, you are able to GF / MF all level 85 areas and boss areas... and support 8 player games and kill off monsters with ease.
This is not just a Hell Trav GF build.
DO NOT use howl as a trav barb. You want them to come at you. You really don't want them to flee from you. You'd be loosing a lot of time if you start casting howl and chasing them.
This is not a pitzerker. I know the build is using the same skills, synergies and horking, but the gear and the strategy is completely different.
And if you want to play it as a pitzerker, then you would swap all GF gear for MF gear, make sure you have 105fcr (cuz you mostly tele when elite sniping) and THEN use howl to scare away the trash mobs so you can better target/hork the elites.
You wouldn't be farming areas lvl 85 and bosses (you can't hork bosses anyway). You'd be farming TZs when they're good, else going back to trav with GF gear and the previous strategy we discussed.
But OP is asking about GF trav barb, so let's keep on track here.
This is some sound advice...
Thanks
