Although Caveira is a defensive Operator, her whole skill set relies on attacking. Use her stealth ability and her speed to stalk an enemy and take them out with a silent weapon.
The pistol almost always injures and downs an opponent unless you shoot them in the head. Use this opportunity to interrogate the enemy and learn the location of the entire team, but do not do so instantly! Many times Operators are paired up and a second enemy will come over while you’re in the process of interrogation.
Caveira’s unique ability is the Silent Step, which allows her to lurk on her prey almost completely silently. For ten seconds, move much more quietly to sneak up on enemies. Only the Luison handgun can be used when the Silent Step is active, and the entire screen will turn a greenish tint. This ability can be used an infinite amount of times, but it only lasts for 10 seconds before needing a 5 second recharge or cooldown period.
Additionally, Caveira can interrogate any knocked down enemy Operators. Approach an incapacitated Operator to see the option to interrogate. Doing this will reveal the ID and current position of all living enemy Operators for several seconds. The Operators will also be notified of their position being compromised.
