- For the Diablo II version of this spell, see Energy Shield.
Mana Shield is a protection spell that allows mana to drain instead of your health while enemies hit you. In Diablo I at least, no matter how many times you trained the spell, it would still consume 33 mana per use. At higher levels, the mana shield was supposed to be more efficient by absorbing more damage per mana point. The effect is canceled when the player enters a stairwell or a portal, or when their mana runs out (even if you use a mana potion afterwards, the effect will have already disappeared).
