Become Familiar

While casting the spell, the target(s) of the spell must be withing reach.

You become connected with the target creature.

While the target is within 100 feet of you, you can communicate with them telepathically. Additionally, as an action, you can see through the target's eyes and hear what they hear until the start of your next turn, gaining the benefits of any special senses that the target has. During this time, you are deaf and blind with regard to your own senses.

As a bonus action, you can perform the help action on the target  on any perception and investigation checks made using vision and hearing. 

Finally, when you cast a spell with a range of touch, the target can deliver the spell as if it had cast the spell. The target must be within 100 feet of you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll.

When you cast this spell again, the previous spell ends immediately. 

You can add another target to the spell when you cast it at 3rd, 5th, 7th, and 9th levels.
