Boss BWL cycles between life draining or power draining passive, depending on how you tag in your heroes. He starts with life draining passive, and switches to power draining passive upon first tag in. Deathstroke is not so effective, as his ice form runs out of power or life so quickly that you can hardly do anything effective. EPI has a good healing passive, which counteracts the life draining passive well. However to be effective, I needed the 5 Darkness stacks from Raven, which can challenging to maintain. I didn't do well with this pip. BWTD seems to be effective with God Killer Blade, as her damage primarily doesn't come from her specials. So power draining passive doesn't hurt her much, and what you need to do is to trap him at corner and unleash unlimited combo. Despite that, it isn't so easy to use her, as I needed to keep her alive. Boss BWL hurts quite a lot, esp with his unblockable Sp2. My BWTD was forced life drain when my team was down to 2 members. What I initially planned out to complete in 2 pips, I only managed to complete in 4 pips. Gutted, but accepted it. It's difficult to find time to play game nowadays. Many times I only get to play before I go to bed, or while commuting. So I'm definitely NOT at my best form recently. Even so, I like to make these effort to upload my videos, even when they are terrible. I am generally a FREE TO PLAY player, so I don't own powerful artifacts like beta club, sword of sin & salvation. I work with whatever that is given free.
