Arsenal Guardian

Bound. The sword guardian is magically bound to an amulet. As long as the guardian and its amulet are on the same plane of existence, the amulet's wearer can telepathically call the guardian to travel to it, and the guardian knows the distance and direction to the amulet. If the guardian is within 60 feet of the amulet's wearer, half of any damage the wearer takes (rounded up) is transferred to the guardian.

Regeneration. The sword guardian regains 10 hit points at the start of its turn if it has at least 1 hit point.

Spell Storing. A spellcaster who wears the shield guardian's amulet can cause the guardian to store one spell of 4th level or lower. To do so, the wearer must cast the spell on the guardian. The spell has no effect but is stored within the guardian. When commanded to do so by the wearer or when a situation arises that was predefined by the spellcaster, the guardian casts the stored spell with any parameters set by the original caster, requiring no components. When the spell is cast or a new spell is stored, any previously stored spell is lost.

Arsenal. The Arsenal Guardian can equip up to two weapons, and store one backup, when an equipped weapon is fired, it will automatically equip its backup weapon and free up its backup slot.

Weapon Loading. The wearer of the guardian's amulet (or anyone whom the wearer commands the guardian to allow) can give the guardian any melee weapon to wield, so long as the guardian currently has no more than three weapons currently equipped. The guardian becomes proficient with any melee weapon, however, if the weapon is magical and requires attunement the guardian is attuned to it only if the wearer of it's amulet is.
