Army of Ruin

Challenge here is keeping the boss alive. I achieved this by having an elven bow and AOE +Projectile/projectile speed/knockback/attack size screen clear build. As I kited, I kept an eye on the boss marker and as soon as it respawned and relocated, I would run in an opposite and diagonal direction so the boss would take minimal damage. There is probably a more optimized build that doesn't screen clear and won't damage the boss as easy, but I preferred just staying away from the boss and maintaining the best screen clear build.
