Mana is the magical energy that serves as ammunition in Hexen. It comes in two forms, Blue Mana and Green Mana. The first weapon of each class consumes no mana, the second uses blue mana, the third is powered by green mana, and the fourth requires both varieties. In addition to containers of blue and green mana, there is a Combined Mana container that provides both types in one package. Thirdly, an artifact called Krater of Might fills both mana types to the maximum once used. The player can store 200 mana of each type regardless of class.
The weapons of Hexen consume the following amounts of mana per shot.
|Blue Mana||Green Mana|
|Hammer of Retribution||0||3†|
|Mace of Contrition||0||0|
|Arc of Death||0||5|
† The weapon can be used without mana but with lessened melee damage potential, and, in the case of the Hammer of Retribution, no projectile.
