Scroll of Beast Bond

You establish a telepathic link with one beast you
touch that is friendly to you or charmed by you.
Until the spell ends, the link is active while
you and the beast are within line of sight of each
other. The beast can understand your telepathic
messages to it and it can telepathically
communicate to you. While the link is active, the
beast gains advantage on attack rolls against any
creature within 5 feet of you that you can see.
