• Unholy Transformation is not always paired with unholy blight in AOE.
• Unholy Transformation check on pet buff in stead of on unholy pact buff (because unholy pact runs out before dark transformation if you have the deadliest coild legendary equipped).
• Epidemic should be used only on 4 targets and up if the legendary deadliest coil is equipped, even if dark transformation is not active.
