The Landmarks of Aetolia are seven specially-designated 'landmarks', each with a good and evil aspect to them. For each landmark, there is a unique way of influencing its aspect.

The effect on the game that the Landmarks have is primarily on the gaining of devotion, if you are a Paladin or Priest, and on the gaining of life essence, for Necromancy. The 'balance' of the Landmarks modifies the amount of devotion or life essence received. The balance means how many of the Landmarks are in their 'good' aspect, if you're speaking of devotion, or how many are in their 'evil' aspect, if you're speaking of life essence. The modifiers are as follows:

See HELP DEVOTION and HELP NECROMANCY for more details on devotion and life essence.
