Caretaker

Arcane Echo. The caretaker cannot cast spells.  However, if they are targeted with a direct spell from ANY kind or source, they can absorb this arcane energy and project it on their next turn.  If the spell is a leveled spell, it will be one level higher when cast from the caretaker's body. If a caretaker is struck by multiple spells before its turn, it will reflect all spells at the same time.

Multiattack. The caretaker carries no weapons.  However, it can pick up any small object and either throw it as a ranged attack, or strike with it as a melee weapon.  If no object is within reach to take up, the caretaker will use its hands to attack.  The caretaker can make two melee attacks, or one ranged attack, per round.

Melee. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 4) damage, which will be of a type created by the object used.

Ranged. Melee Weapon Attack: +14 to hit, range 60ft, one target. Hit: 12 (2d8 + 4) damage, which will be of a type created by the object used.

"I'll take that".  The caretaker has the ability to take an object within 5' from someone, to use as a weapon or to throw away.  A contesting strength check will determine if it is successful.  A caretaker can only hold one item in each of its hands.  If the item is magical in nature, the caretaker will absorb the arcane energy within and render it "non-magical" for 3 rounds.

Avoidance.  If it can see an attack (melee or ranged weapon) coming, once per turn, the caretaker can choose to avoid the attack, taking no damage.
