This spell binds your life force to that of a bonded familiar.

While this binding lasts, you and your familiar may freely use hit points from each other as needed (i.e. if one or the other is wounded, the damage may be taken from the other’s hit point pool, or split between the two in any ratio –the master always decides). This occurs as a free action and takes no concentration on the part of either master or familiar. In addition, while the binding lasts, both you and your familiar are immune to death from massive damage and spells that cause instant death or automatic failures on Death Saves.

If either you or your familiar are dropped to 0 hit points while this spell is active, the other must make an immediate successful Constitution save or suffer 1d6 points of temporary Constitution damage in the effort to keep the other alive.

Regardless of the outcome of the save, the target that was dropped to 0 hit points is instantaneously (as in before actual death occurs) healed as per a heal spell (same caster level as the original life bond), and the bond is broken.

Life bond can only create a bond between a master and one familiar at a time.
