Animal Haven

You ward a Beast companion creature within range against attack, and provide it with 1d4 Temporary HP.  The Beast must consider the caster as an Ally, (either due to Animal Handling, Charm, etc.).  Until the spell ends, any creature who targets the warded Beast creature with an attack or a harmful spell must first make a Wisdom saving throw. On a failed save, the creature must choose a new target or lose the attack or spell. This spell does not protect the warded creature from area effects, or effects that do not target the Beast directly.

If the warded creature makes an attack, casts a spell that affects an enemy, or deals damage to another creature, this spell ends & The Temp HP are removed.
