Chameleon

Mechanics
In casing mode, players are restricted from doing certain actions that they would be able to do when masked, but it allows them to case the map and look for any key points, areas of interest or for guard patrols without being noticed by civilians.

The basic version of the skill allows for special enemies to be spotted during casing mode and the aced version allows for anything that can be instantly interacted with to be interacted with in casing mode, including loose cash and keycards.

Strategy

 * This skill is solely intended for stealth, with no significant application for it outside of stealth.
 * The basic version of the skill can allow for guards to be spotted and then tracked through walls. This can help with observing guard patrol routes, and knowing when you're in a safe area or not. This can be helpful on maps such as Shadow Raid or Brick Bank.
 * The aced version is very useful. Four Stores can be partially completed without even going outside of casing, as loose cash and key cards can be picked up and used to open certain doors. There are two exceptions to the instant pickup, being safes and documents in the Golden Mask Casino heist.
 * You can pick up body bags in casing mode, even though they aren't instant use.
