Herald hammer in wvw it's a nuke build with high reward high risk of fail, that's why you wandered around backline of zerk boon up ppl, works better if you sync with your commander for pulls or boon strips It's a advanced build for experienced players or better say non-newbie friendly You basically bet all your damage into a single skill hopping to single down most of the enemy zerk if there's no freaking aegis or scourge shields up lol
