Frost Nova is undeniably fun, but does very little damage. I was was thinking something along the lines of unique boots or gloves that have +to all skills or cold skills or frost nova/mana regen/-enemy cold res/and "your frost nova does double damage". OR simply buff Frost nova with synergies and/or increased damage. It would allow sorceresses to have an easier time running inferno cows (frozen enemies), and I think that it would be a really entertaining build!
