Actions

Multiattack. The Deathworm Infested makes two attacks with its claws and uses Burrowing Worm.   Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 1d6+3 slashing damage plus 2d6 necrotic damage.   Burrowing Worm. A worm launches from the Deathworm Infested at one humanoid that the spawn can see within 10 feet of it. The worm latches onto the target's skin unless the target succeeds on a DC 11 Dexterity saving throw.
The worm is a Tiny undead with AC 6, 1 hit point, a 2 (-4) in every ability score, and a speed of 1 foot. While on the target's skin, the worm can be killed by normal means or scraped off using an action (the Deathworm Infested can use this action to launch a scraped-off worm at a humanoid it can see within 10 feet of the worm). 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 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 Deathworm Infested. If a worm-infested creature is targeted by an effect that cures disease or removes a curse, all the worms infesting it wither away.
