Cloak of Invisibility Technique (Earth-2356)

The user covers themselves with a cloak that has a colour and pattern matching the nearby surroundings, concealing their presence by seamlessly blending in. The user can then gather intel from their position or wait for an opportunity to stage an ambush on unsuspecting targets. Although skilled Jedi can make effective use of this technique, unskilled Padawans could be particularly ineffective; Konohamaru Sarutobi routinely used poor disguises, such as trying to blend in with a fence using a horizontal pattern rather than a vertical one.
