This magic key has two main abilities, one is to open locks in the manner of a magic skeleton key, and the other is to associate a lock with a person or group of persons.
- The first use is pretty obvious, you merely insert the key into a lock, and the key will change shape and spin around and physically move the tumblers or mechanism to open the lock. The key will have trouble with large locks or small, it can stretch from half to double its natural size, so depending on the key and lock combination may or may not function.
- The second use requires a keyword, and is more subtle. When the keyword is spoken, the key will attune itself to anyone who holds it; and then after the key is inserted into a lock, the lock itself will attune itself to the key. In that way only that particular holder of the key may open the lock. The magic is such that anyone who holds the key before the key is inserted into a lock will become so attuned; meaning you can have a group of people be able to open the lock with that key, but anyone not so attuned will have unlocking attempts fail. If an original key for the magicked lock is used, it will no longer function.
