Empathic Bond

You touch up to one willing creature and form a spiritual bond to them. For the duration of the spell, gain the following effects :

• You always know the location of all bonded creatures, relative to your location. They also know your location relative to their own.
• You know how many remaining hit points each creature has, and they know how many remaining hit points you have.
• When any bonded creature regains any number of hit points, they can add your spellcasting modifier to that number. 

If a bonded creature drops to 0 hit points, or if they are ever on a different plane of existence than you, this spell will no longer effect them. The spell also ends if you cast it again.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target and bond to one additional creature for each slot level above 2nd.
