Broodmother

Legendary Resistance (1/day).. If the broodmother fails a saving throw, she can choose to succeed instead

Combined Resistance. When all limbs are attached, the broodmother is resistant to all non-magical slashing, piercing, and bludgeoning damage.

Limb Structure.
Each of the broodmother's body parts are

• Left Arm (2 Structure)
• Right Arm (2 Structure)
• Left Leg (2 Structures)
• Right Leg (2 Structures)
• Tail (3 Structures)
• Head (4 Structures)

 Called Shots may be made against a body part; the attacker has disadvantage on the roll, but if it hits, on top of normal damage, the body part loses 1 Structure. Critical hits, whether called shots or otherwise, reduce a body part's structure by 1. If a part's structure is reduced to 0, the broodmother loses the use of the associated ability.

Multiattack.. The broodmother uses Tail Grapple or Acid Spray, and then makes up to 4 Limb Strike attacks, one for each intact arm and leg.

Limb Strike.. Melee Weapon Attack: Roll: +9, reach 10 ft. , one target Hit: 15 (3d6 + 5) Slashing damage.

Tail Grapple (Tail). A target within 30ft. must make a DC16 Strength saving throw or be grappled and pulled to within 10 ft. of the broodmother

Acid Spray (Head, Recharge 5-6). The broodmother exhales acid in a 30-foot cone. Each creature in the area must make a DC 16 Dexterity saving throw, taking 28 (8d6){"diceNotation":"8d6", "rollType":"damage", "rollAction":"Acid Spray", "rollDamageType":"Acid"} acid damage on a failed save, half on success

Spawn Hatchlings (1/Day). The broodmother shrieks and expels 1d6 Hatchlings on unoccupied spaces within 10 ft. of the head.
