The Revel: Key to the Lord's Chamber

[Providence]

I think his key should be FOR 1 RESET ONLY (like other items that despawn on reset.)
The reason being that I forgot I had one from the last time I did this and just brutally screwed up my team that wasn't ready by opening the door when I just meant to 'fail' the 'pick lock' check. I managed to kill  five people, if you count myself.
