Innate elementa meleel u have to have life and mana on melee attack life and mana leech dosent work. Just to clarify... mana and life on melee attack wont work with Cherubim as its a "projectile" same goes for "Rend" on teddy bear Only LAEK and MAEK will work with elemental dmg.
In the tank section of the build someone pointed out you have +1 hive point when you already have 2 coven skills via ice queen and charged armor. My guess is you had some sort of item that gave + to Hive for pre buff?
