This warcry boosts damage substantially. The amount of Fury required sounds considerable, but in the BlizzCon demo a Barbarian of around lvl 6 or 7 had about 100 Fury, and regenerated enough of it could fill the bulb in a battle with every hit to keep using his basic Fury-consuming skills. So dropping 50 on a WarCry depleted about half the total, but was prettyjust 4 or 5 enemies.. the amount of Fury it cost The duration at level 1 wasn't a problem in terms of exhausting all the fury -- it was a problem in terms of building up that much in the first place. It required a good sized pack of monsterslong enough to last between battles, since you'd need so players had to kill 4 or 5 remember to get cast this one as soon as they had enough Fury , just after a battle started. Remembering to use this skill. Once recast it during longer battles was in effect the rest of the battle went trickier. Presumably more quickly, thanks points will add to the damage bonusduration, but that's not yet known.
