on rightclick with blaze rod:
    if name of tool of player is "&6Fire":
        set {_waited} to difference between {col.%player%.lastused} and now
        if {_waited} is less than a minute:
        message "&cYou have to wait %difference between a minute and {_waited}% before you can use this command again!"
