Seeker Abilities (Armor Proficiency):

Modification-Point Cost: 1 per type of armor.

If you expend 1 Modification-point to proficiently wear leather armor, you can wear all types of leather armor without having the penalty of -10 to all defensive rolls (i.e., light, heavy, scale, troll-hide, dragon-hide, and borgus leathers would be included in this).
