Gear up your Afallen until she can start surviving. Legendary Lv30s or Gold Gear Lv40s are enough with Awakening 4. Purple maxed out gears also seem to be enough this. For this specific boss, for maximum guarantee, you can use Phys DEF leaning equips (armor/accessories). Keep in mind future Broken Lands 4 bosses might be different. In terms of enchant attributes, prioritize Phys DMG Reduction but if you're specifically dying to his trample, then Mag DMG Reduction might be worth considering (you can bypass trample if you deal enough dmg but with this strat, you'll likely need DPS setup in that situation). In general, DMG Reduction enchant attribute is high priority for tanks.
