Decoy

A  is a type of ability which is used to distract enemies.

Summary
A decoy ability attempts to draw an enemy's attention towards the ability, allowing the user to catch them out whilst they are distracted.

Some decoy abilities have the ability to "fake out" their opponents, giving them a 50/50 decision of whether the ability has been properly used in a way that poses a threat to them or whether it's just a harmless fake. Even without dedicated mechanics for faking, some Mobility abilities can also utilize their sound effects to act as a fake by casting them in place or cancelling them during their channel. This will cause enemies to consider you at a different position or elevation on the map instead of taking a fight at a standard angle.

Guiding Light can also act as a fake by causing enemies to shoot or turn from it without even activating the flash, potentially allowing a quicker response from allies to take out the enemy.
