Mana

Mana and health bars are shown in the top left of the screen

Mana is the energy that fuels all active powers in the game. It can be seen as a blue bar underneath the health bar in the interface. Running out of mana does not have any penalty, but the player must wait until it recharges (sitting is the fastest way).

Even if mana cannot be reduced by normal attacks, mages are able to attack an enemy's mana bar. The spells Energy Borrow and Sadistic Servants steal mana from a foe and add it to one's own supply, and the spells Mana Burn and Evendim's Fury turn enemy mana into damage.

Barbarians can also attack the mana bar with the power Rend.

Mana pool

Intelligence is the only base attribute that increases a character's full amount of mana. The amount is is calculated by:

mana points  =  level x 18 + intelligence x 9 - 80

So for example, a level 35 conjurer with intelligence at 69 will have:

35 x 18 + 69 x 9 - 80  =  1171 mana points

Or a level 17 knight with intelligence at 33 will have:

17 x 18 + 33 x 9 - 80  =  523 mana points

Naturally mages, with intelligence as their primary attribute, are the class with the largest mana pools, with archers second and warriors having the smallest. Mages and archers are also able to increase their mana with passive powers: for mages Dragon's Blood increases intelligence and Mana Pool increases theire total mana; for archers Wits increases their intelligence.

Regeneration

The speed at which a characters mana regenerates is determined by the size of their mana pool. In normal (non-combat) mode, mana regenerates at 0.008 mana per second per point of mana. So a character with a mana pool of 1000 will have a mana regen of 8 mana per second, a character with 2000 mana: 16 mana per second etc. It is commonly believed that mana regeneration is goverened by the character's intelligence; however intelligence only indirectly increases mana regen by increasing the character's mana pool in the first place.

In battle, mages can regen their mana quickly using the power Ambitious Sacrifice, as well as the mana-stealing spells mentioned above. Other classes have no mana regeneration spells, so as well as their natural regen they have to rely on mages to give them mana using with the powers Synergy Bond and Mana Communion.
