Burrowing Worm of Kyuss

Burrowing Strike. This worm launches from a spawn of Kyuss or an infected victim's body at one living target within 10 feet of it. The worm latches onto the target’s skin unless the target succeeds on a DC 11 Dexterity saving throw.

While on the target’s skin, the worm can be killed by normal means or scraped off using an action. Otherwise, the worm burrows under the target’s skin at the end of the target’s next turn, dealing 1 piercing damage to it.

At the end of each of its turns thereafter, the target takes 7 (2d6) necrotic damage per worm infesting it (maximum of 10d6). A worm-infested target dies if it drops to 0 hit points, then rises 10 minutes later as a spawn of Kyuss. If a worm-infested creature is targeted by an effect that cures disease or removes a curse, all the worms infesting it wither away.

Burrowing Strike. The worm uses its Burrowing Strike ability if it is not already attached to a target or inside a target.
