PoE 3.19 added a new Ring base item type: Bone Ring.
Bone Ring
This Ring has an Implicit Minion Elemental Resistances modifier, and can roll Minion-related modifiers.
Minion Elemental Resistances modifier: Minions have +x% to all Elemental Resistance. Note that Chaos damage is not elemental, thus "+% to all Elemental Resistances" does not affect chaos, but "+% to all maximum Resistances" does.
Neither passive skills nor stats from the player’s equipment affect minions unless they specifically state “Minions _____”.
Life flasks can have a suffix that grants minions a part of the life flask recovery. This effect works even when the player has full life or Chaos Inoculation. If a player has equipped Umbilicus Immortalis – flasks effects apply to their spectres and zombies.

Minion Damage
Damage Types – Zombies, Animate Guardian, Animate Weapons, Holy Relic, Sentinels of Dominance, Sentinels of Purity, Skeletons and Stone Golems deal physical damage, Spectres and Dominated deal whatever damage they did before they died, Raging Spirits deal physical damage of which 50% is converted to fire (much like Infernal Blow), and the four other Golems do damage in accordance with their names (chaos, fire, cold, lightning).
Critical strikes – Most minions have a base critical strike chance of 5% and a base critical strike multiplier of 1.3 times the damage. Raise Spectre and Animate Weapon are capable of creating exceptions to these previous 2 rules. Minions gain the charge benefits of monsters, which means each power charge is +200% increased critical strike chance.
