Magic Items

Animated Shield
Armor (Shield), Very Rare (Requires Attunement)

While holding this Shield, you can take a Bonus Action to cause it to animate. The Shield leaps into the air and hovers in your space to protect you as if you were wielding it, leaving your hands free. The Shield remains animate for 1 minute, until you take a Bonus Action to end this effect, or until you die or have the Incapacitated condition, at which point the Shield falls to the ground or into your hand if you have one free.

Amulet of Health
Wondrous Item, Rare (Requires Attunement)

Your Constitution is 19 while you wear this amulet. It has no effect on you if your Constitution is 19 or higher without it.

+3 Rod of the Pact Keeper
Rod, very rare (requires attunement by a warlock)

"Formed from the severed tentacle of a powerful star spawn, this rod plagues its wielder with dreams of alien creatures that beckon them to travel deep within the Thunder Peaks, where something patiently awaits their arrival."

While holding this rod, you gain a +3 bonus to spell attack rolls and to the saving throw DCs of your Warlock spells.

In addition, you can regain one spell slot as a Magic action while holding the rod. You can't use this property again until you finish a Long Rest.
