Start boss fights with Dancing runic wep, use marrowrend. Keep as high as stacks of bone shield up as you can. Death strike isn’t the spam use it used to be. You will want to utilize bonestorm and it to keep healed, as well as the blood siphon ability i forget its name on, but is like the first tier of talents.Use DeathStrike after BIG hitting abilities or if you get hit hard, as now instead of just healing it heals back a % of damage dealt to you in a timeframe. You won’t be able to keep blood shield up super easily due to having to keep boneshield up, but bone shield is enough with rune tap as a secondary defense CD.
