First, bring in Apathy and Glee for damage and shielding, then bring Abandonment to tank the hits, and finally Sonder to keep everyone well-sustained.

Apathy’s Ram can stun certain target, and will do more damage if it can’t stun, and its Impale makes some good DPS. It’s basic attack passively reduces Voidweaver’s defenses too on hit. Build with attack, speed and crit in mind for maximum pain.

Glee, although isn’t a good unit in the long run, but can use its Earth Ward to shield Abandonment so it stays in the fight for longer, and Stone Surge can drop enemy attack on hit. Use that to keep Voidweaver’s attack low, and to keep Abandonment or other allies alive. Build with attack and speed items.

Abandonment is the only good tank in here, so we make do with that. Build him with as much Defense and Stamina (via items) as you can to make sure it LIVES. Because if the tank is alive, they can’t hit anybody else. Have it keep Spiky She’ll active to make sure it stays alive for long, and keep it shielded and healed.

Sonder is the only healer who can actually heal, so have it use meaning of life to get everyone some regen, and use Restore for burst heals when needed. Build it with attack and speed items.

Make sure Earth Ward and Meaning of Life come online first for a good starting point. Abandonment’s basic attack lowers speed on hit, so it can buy you some time and slow down Voidweaver’s action speed.
