Survivor Perk: Take Cover
You make use of obstacles in unexpected ways.
Performing a fast vault at a pallet while holding the crouch button will cause you to slide under the pallet.
This perk then goes on cooldown for 60/50/40 seconds. Using this perk again while it is on cooldown will cause Exhaustion for 60/50/40 seconds.
Take Cover cannot be used while Exhausted.
Your hitbox is much smaller while sliding under a pallet, making you immune to basic attacks. However, you can still be interrupted at the start of the animation and certain attacks will still be able to hit you (hatchets, corrupt purge, demon strike).
I didn't think this perk was strong enough to be a full exhaustion perk, but I still think there should be a penalty for using it repeatedly, so I decided to make it a "light" exhaustion perk. This means you can't use Take Cover after using another exhaustion perk or use another exhaustion perk after using Take Cover, but you can use Take Cover once and then use an exhaustion perk.
Feedback is greatly appreciated!
