This stupid OP campaign asset can easily trivialize the entire Scarlet Keys run, especially when you get it online early enough. Healing investigators for 1 damage and 1 horror at the same location pretty much means you do not have to worry about any semi-evenly distributed trauma. Let's say you are in a 2-player game and both have mental and physical trauma. When the game starts, you heal 1/1 immediately. Then, when an enemy shows up, you deal any amount of damage to it and begin what can easily turn into an infinite loop of healing investigators and one enemy till your heart's content. If you can evade the enemy, you can buy yourself a ton of time and shift the key again round after round, keeping a healthy amount of restoration with minimal investment of actions/resources to keep at least 1 damage on an enemy. The game presents numerous ways of doing that from a distance OR with minimal danger. I strongly advise house ruling this thing out of your games if you want a real AH game and not some trivial stuff.
