you could keep either Glasscannon or Push the Limit, but not both. if you still have issues casting spells, get rid of both, but keep Masochism, as that will keep your Health around 50%, which means your Blood Magic is giving around +100% damage. if you do get rid of both, either Dodge or Crit Chance.
you need more Crit Chance, or you will not be doing very many Deadly Strike/Brutal.
take off Shield wall Proc & replace with Dodge.
take off +5000 Poison on Sword and replace with +100% Weapon Damage. on Stat Page, I guess split your Stat Points between Mana & Power. Wizards get an All Resist bonus with Mana, and Blood Magic switches the Mana to Health, so you get both benefits. I guess 2 or 3 Points in to Mana for each Point into Power. the +100% Weapon damage will really boost damage from the Power Stat a lot more than you are getting from +5000 Poison.
