Animated Jade Serpent

• The serpent is a construct that understands and obeys whoever was holding the staff when it transformed.
• It has immunity to poison damage and the poisoned condition. It doesn’t require air, food, drink, or sleep.
• When it drops to 0 hit points, roll a d6. On a roll of 1, the snake turns to dust and is destroyed. On any other roll, it changes back into a staff and breaks into 1d4 + 1 pieces that must be magically mended before the staff can be used again.

Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 6 (1d4 + 4) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one.
