• Prereq: 5 adds in the chosen skill
Player character Storm Knights cannot normally increase their skill adds to more than +5. But some are adept at very specific skills, such as a world class marksman, a top computer hacker, or a master swordsman.
The Mastery Perk allows your hero to increase any one skill beyond +5 adds to a maximum of +8. Skill adds are still purchased with Experience Points—the Perk simply allows you to do so.
Prowess is a general category that can be taken by any character from any cosm. It focuses primarily on Perks that can be used in combat.
