There are three types in the game: light, medium and heavy armor. Heavy armor is quite rare and never used under the oppressive heat of the sun.
Light armor will consist of: Leather Lamellar
Medium armor: Chain mail Scale mail
Heavy Armor: Banded
Light armor will grant you a 1 in 6 chance to stop 1pt of cliche damage
Medium armor 2 in 6.
Heavy Armor 3 in 6.
The disadvantage of armor is fatigue and so after every 10rds of combat (1 minute), the wearer will incur a 1pt penalty to all his cliches. This penalty cannot bring you down to a Zero.
Light armor's max penalty is 1pt. Medium armor's max penalty is 3pts. Heavy armor's max penalty is unlimited.
It takes 1 hour of rest to fully recover 1pt of fatigue loss.
Underground where there is no sun or heat, Fatigue accrues every 20rds. instead of 10.
Spellcasting while wearing armor will have the same chance to fail as it has to stop damage. This roll is taken immediately after the spell is being cast by the GM. Failure indicates the spell fails and nothing more can be done that round. i.e. if the spellcaster is wearing light armor, he has a 1 in 6 chance of spell failure.
