Few few mistakes coupled with panic! Let Blackhand off the hook. Phase 1 and 2 seemed not cause us too much problems. Slightly different tactics here for Phase 3, see what you think?
Getting hit by Impaling Throw makes positioning difficult, if it does not knock us off the edge in phase 3. Attach Slag Bombs is also something that I had to deal with along with Massive Shattering Smash, making phase 3 quite tricky for tanks.
