Amulet of the Troll

This amulet is made of a grey-green gemstone, enclosed in a troll's claw. On your turn if you have less than half your hp remaining, you regenerate 10 hp.

Whenever you take at least 15 slashing damage on a turn, roll a d20 to determine what happens:

1-5: Nothing else happens

6-10: The damage is halved, as the cut seems partly heal quickly.

11-14: One of your arms is severed if you have any left.

15-18: One of your legs is severed, if you have any left. 

19-20: Your head is severed, and you will die within 5 minutes if it is not reattached.

Severed limbs can be reattached if they are reattached within one hour of being severed. 

A severed leg is unable to attack and has a speed of 5 feet.

 A severed arm has a speed of five feet and can manipulate items, but cannot attack. 

If your head is severed, your body is still under your control, but is blinded unless your head can see it.

 With a leg missing, your speed is halved. With no legs, you can crawl if you have both arms. With one arm, crawl speed is halved. With no arms and legs, you cannot move or benefit from any bonuses to speed.

Notes: Attuning to this item takes three hours instead of one. Ending your attunement deals 2d10 piercing damage to you, as it has symbiotically melded into your chest.
