We all know that BF is an annoying area boss. As a Drk (Melee), half the time our attacks will not hit the target because it's constantly jumping around. I figured a method that can kill BF most effectively as a Drk. (after having struggles of my life to kill one) It includes the obvious rush-corner pin but once I start hitting the BF, timing is everything. The trick is to pin the BF to the corner, wait for it to turn its back on you then start hitting after a mili second. BF will turn around after every hit, allowing you to hit it constantly without a pause. <You can see at one point in the video that I hit 99 times in the same spot> HOWEVER, there will be occasions where this BF won't turn its back on you after you have hit it on its front. This is where the offbeat timing comes in. Hit it twice on the front, take a milisecond break, letting it turn around and show its back to you. If you hit it too early at this point, your attacks will hit blank and let BF run toward you. If your timing goes wrong at any point (missing the attack and letting BF rush to you), move back a bit and rush-pin the BF again to the corner then repeat the steps. All my explanation were foreplayed in the video. Although it lags a lot, please abide with the fact that I have a horrible internet connection. In this video, my Drk lvl 159, equipped with skyski (normal att speed) with ~7100 range (with mw20) soloed BF in 7min using heartstoppers.
For new heroes using sparta/st, same technique but dont use ur sword boosters, that'll prevent some attacks from missing
I only used my mage during that video . I always solo without one and it takes me an extra minute or two.
