To all intents and purposes they yield identical damage output, but ruin 2 also inflict blindness and costs slightly more MP. Due to aetherflow restrictions, both fester AND energy drain can be cast 3 times per minute, and fester does infinitely more damage than energy drain (Up to 400 potency - Bio + Bio II + Miasma + Miasma 2 - Vs 150 for energy drain)
