Guild Wars 2 Living World Season 4 Descent - E6 War Eternal

In order to damage the Torment, you must evade the Crystal Dragon's Fist attack and its subsequent shockwave, then use   Dragonsblood Spear the Dragonsblood Spear to pin it down. You can then attack the fist until Drain Beam Shattered wears out, or specific health thresholds are reached (70%, 40, and 10%). In the mean time, do your best to avoid Crystal Eruptors; the few regular Branded enemies can be ignored.
