I used a shard of hate in cube earlier and it looks like it's proccing 100%. I was using Shock Pulse- Piercing Orb and Energy Twister-Mistral Breeze and every attack had a SoH proc with it. Not sure if this is an exploit or not but I remember something a long time ago about SoH internal CD being nerfed because it was overtuned. Maybe it got screwy in the new cube? If someone wants to give it a try and confirm.
