mana shield or no?

well the bad thing is that if u haev little health, and a monster in hell attacks you, if u use mana shield like all your mana will be gone, also mana shield sux in duels because u lose all mana when someone attacks you so it can help save you but for a price of losing mana so u will need mana potions and stuff

If you can afford it, stock up on 70/15's. But to get 39 of those... shit how many 290's? Never traded for one.
