It's kind of hard to determine if kills from a bloom explosion count as nova bomb kills. Since they are kills, they will of course give you some super energy. Inverse shadow will increase the super energy you would normally get from one of those kills anyway. My guess is that the Insatiable perk for NB kills does NOT proc on bloom kills. The issue can be tested. But since bloom works so well with axiom bolt, and energy drain doesn't stack, I tend to just enjoy the mayhem and not worry about the details. I wish bloom procced on all void kills. We need more skill/weapon interactions. Sunsingers touch of flame and Viking funeral should proc on solar weapons too. Warlocks should be the burst dps kings. Titans can make orbs from heavy weapons and normal melees, and hunters have plenty of weapon affecting skills. Warlocks gaining extra effects for specific weapon elements would be cool without being OP. Especially if these only procced on pve kills.
