Chaser

X-Ray Vision. You can see through anything, no matter what's covering your eyes except your own skin.

Super Speed. You have the uncanny ability to move fast, at least faster than the eye can see. Immediately wins the roll-off for the dodge reaction. Adds 1 use and deducts 2 rooms from the cooldown of the Dash action. 

Multi-attack. The Chaser makes two Claw/Bite attacks. Cannot be used twice in a row. Must visit 4 other rooms before you can use it again.

Claws. Melee Attack Roll. Roll 5d6 to hit and for damage.

Bite. Melee Attack Roll. Roll 5d6 to hit and for damage.

Dash. Allows you to get to 2 rooms quickly, 2 times. Cannot be used twice in a row. Must visit 3 other rooms before you can use it again. Due to your Super Speed, you can use this action 1 additional time while also only needing to visit 1 other room before you can dash again.

Every action can be done as bonus actions, but restrictions still apply. But +1 more room. Legendary Actions are an exception, and are not included.

Dodge. Add 1d6 to your defense. Must win a Dexterity Check roll-off before you're allowed to use this.

Claw Tempest. Melee Attack Roll. Roll 1d20 to see if it's inescapable. Then roll 6d10 to hit and for damage. Cannot be used twice in a row. Must visit 5 other rooms before you can use it again.

X-Ray Vision. You can choose 3 from the 8 cardinal directions for which direction you'd like to scan. The moment a person is swept by your vision in the direction you chose, you can clearly see them. However, your ability cannot be used while running, as your senses cannot keep up with your speed. So you must be quick, cause if not, the target you saw may or may not be in the room you saw them in anymore. Cannot be used twice in a row. Must visit 5 other rooms before you can use it again.
