Mana depletes when a spell is cast. Without Mana the spells will have no "energy" and thus will not work.
How to replenish Mana? Edit
- The normal way to replenish Mana is to consume Mana Potions, found in loot.
- In Overlord II it is enough to stand close to a Tower gate.
Overlord & Raising Hell Edit
- Maximum: 8
Overlord II Edit
- In Overlord II, mana is increased by acquiring Mana Upgrades. There are a total of five such upgrades to be found in the game.
