Flask of Holding

This stoppered bottle contains an unknown imprisoned spirit. Opening the bottle frees the spirit. It will fight for you for ten minutes or carry out a task that lasts up to an hour. If you order it to carry out a suicidal order, the compulsion is broken and it is free to leave or attack you. Once the time is up, the spirit is released from its compulsion and is free to behave normally. This item is only useable once.
