There are 3 ways.
Stack skill dmg and shield, its all about use calculated risk and crit a dash burst you can deal 1k. Wait untill you see a shieldless squishy hollowtiwn to get in and finish it off, if fail run!
Stack all attack speed and some dmg. Make every battle 3 vs 1 (teamate, hollowtiwn and you) its all about stay with the team and support.
Get hp, regen and speed. If there are no wave cleaners go Ground Zero and drain dash, kill minions and help anyway you can.
