Dark Armor contains the most diverse collection of powers. Some powers offer resistance, like Invulnerability. Cloak of Darkness boosts defense, while also providing stealth. Dark Regeneration heals you. There are also powers to frighten, disorient, or damage your opponents. Before Issue 3, Dark Armor was considered the black sheep of scrapper secondaries. Now that it is possible to have status protection and damage protection at the same time, expect to see DA grow in popularity. The heavy endurance costs of running multiple toggles is still an issue, though.
