Shade Sentinel

"With 'Revenge' and 'Ghost' as default Precepts, Shade is well suited for stealth gameplay. Shade also comes with a burst laser pistol."

- In-game Description

This is a sentinel for the stealthy. The Shade's cloaking ability can last indefinitely as long as an enemy is inside activation radius. The cloak only activates if an enemy is in the activation radius sphere for the cloak, and Shade's view of the enemy is not obstructed by nearby objects (i.e. Shade is behind an object inside the sight radius that is obscuring it from seeing the enemy, even if your warframe can see the enemy it won't make a difference). Activation is not dependent on the direction that Shade is facing. Warframe abilities will not bring you out of stealth and you will remain hidden, as long as another enemy is close by.

Note that infested Runners will still explode when you are next to them, regardless of being cloaked, and enemies such as leapers, rollers, or ancients that have activated their attack (such as a Leaper getting ready to charge) will still hit you after you cloak if you don't move out of the way. On infested levels, take care around Runners as the explosion could knock you out of cloaking range.

Sentinel Mods
These mods are specifically for the Shade. They grant the Shade unique abilities that the other sentinels can not use. Shade, Dethcube and Wyrm also share some mods. Ranking up the level of sentinels may increase the activation range of these abilities. [UNCONFIRMED]
