Armor Training
Class proficiency — see Proficiencies for the rules and the Proficiency Index for the full list.
The character gains proficiency in armors one weight category heavier than normally permitted by his class without penalty. Armor Training does not grant the character the ability to use thief skills in medium or heavy armor, nor to benefit from proficiencies or class powers that require light, very light, or no armor. Spellcasters who take Armor Training are able to cast spells in the armor they become proficient with.
