Stealth Mastery

Summary
Stealth Mastery is the ability to conceal one's presence for various uses, such as launching attacks without anticipation. There are several ways this could be achieved; sheer invisibility, blending with the environment, thus a background adaptation, skill, or in some cases even technology could get the job done. Any sound suppression may as well fall under this category.

On many occasions, the wielding of Enhanced Senses could counter this ability, as well as any limitations the technique may display, such as movement.
