Blood Bond

You establish a telepathic link with one beast you touch that is friendly to you or charmed by you. The spell fails if the beast’s Intelligence is 8 or higher. Until the spell ends, the link is active while you and the beast are within 100 feet of each other. Through the link, the beast can understand your telepathic messages to it, and it can telepathically communicate simple emotions and concepts back to you; you can see through your bonded animal's eyes, sharing sight, hearing, and even pain. While the link is active, the beast gains advantage on attack rolls against any creature within 5 feet of you that you can see. The link is broken if you dispell it, if you cast it again, or if either you or your bonded animal die. If you cast this spell at 3rd level, its range is increased to 1 mile and its duration is increased to 1 month; if you cast it at 4th level it lasts a year and has a 10 mile reach; if you cast it at 5th level or higher it lasts until dispelled or broken and is active whenever you and your bonded beast are on the same plane of existence.
