You establish a powerful link with one willing creature you touch that is friendly to you or charmed by you. The creature can be any type except humanoid. Until the spell ends, the link is active while you and the target are on the same plane of existence. Through the link, you and the target gain the following benefits:

• You and the target always know your exact distance from and direction of the other.
• When you or the target cast a spell targeting only itself, the spell can also affect the other, given that the other is willing.
• You and the target gain advantage on attack rolls against any creature within 5 feet of the other that the attacker can see.
• You and the target can communicate telepathically, perfectly understanding each other’s telepathic messages regardless of whether you share a language or the target speaks one.

  Before the spell ends, you can cast this spell again to maintain the link for another 24 hours, given that the target is still willing to be bonded with you. Doing so doesn’t require you to be within Touch range, though you must be on the same plane of existence as the target. This use of the spell reaffirms your link with the previous target, rather than establishing a link to a different target.   The link ends early if you cast this spell targeting a different creature, if either you or the target dies, or if either you or the target uses an action to break the link.
