TL;DR Cast dread shade, and bone curse on your golem, and hit it with very fast attacking marrow shards that hits your bone golem, pierces through your golem, and enemies, applying DR debuff, CC, and damage to all nearby enemies with a massive amount of bone golem nova projectiles. Use transplant for mobility, positioning, and executing enemies.
