Burnout

Burnout is an indication of a player's current fatigue level, spells will have an increase in Mana cost as the player's Burnout increases. For Ars Magica 2 v1.1.2 and below, the amount of Burnout a player receives is dependent on their Casting Mode; a higher tier Casting Mode results in a higher Burnout cost.

A player's Burnout is usually displayed as a red bar located at the bottem left of the screen. By default the exact value of your current Burnout is hidden, this can be changed by entering the command /amuicfg and enabling Numeric in the Options tab. The Burnout bar can be moved around in the amucfg window.
