We already have a Bell of Opening that is good for any lock that can be picked.
What we don't have is a way to bypass Rune Locks that require an ability score.
Add a new item to the store "Rune Lock Key" that will work like a Bell of Opening, but will auto-succeed the stat check. This should work on every ability rune lock, including those that reset like the ones in VON5 and Partycrashers, although if the lock resets, it would require additional keys to unlock it each time.
Cost to be the same as a Bell of Opening - also available as a Daily Dice roll option.
I imagine this only to be relevant for Rune Locks, rather than levers that require a STR check. If it worked on those too, I suppose that would be okay.
