Life Connection

SPELL 3
Traditions divine, primal
Cast 10 minutes
Range touch
Targets 1 living creature
Duration 24 hours

When you cast this spell, you place a failsafe deep within the life force of the target that could save them in a time of need. You can sense when the target takes damage, provided you're within 1 mile of one another. A creature can be part of no more than one life connection simultaneously. When the spell is cast, you gain the Defend Life reaction; once you use the reaction, the spell ends.
