Create Pestilence Imps

Note this spell counts as both Transmutation and Necromancy.

This spell takes the collected hands of the plague victims and infuses them with demonic essence, changing them into Tiny Imp like creatures, which appear as twisted and grotesque caricatures of the person whose hand they were made from. Pestilence imps are a lively bunch, who are always on the lookout for new creatures to infect and torment.

The spell does not provide any form of control over the newly created demons.

Actions: Bites. Melee Weapon Attack: +5 to hit, reach 0 ft., one creature in the swarm's space. Hit: 14 (4d6) piercing damage, or 7 (2d6) piercing damage if the swarm has half of its hit points or fewer. If the target is a living creature, it must also succeed on a DC 13 Constitution saving throw or become poisoned. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Swarm Movement: The entire swarm moves together, and can move into and through the spaces occupied by other creatures. Any creature that tries to move through their space must count that 5 foot area as difficult terrain, and must succeed on a DC 13 Dexterity save to avoid falling prone. The swarm can move through any space that only a tiny sized creature would fit through.

Bonus action: Infestation: If the Pestilence Imps end their move in the space of another creature, they can choose to climb all over them, and follow them as they move. The creature they try to infest can make a DC 13 Dexterity save to avoid being infested. On a failure they swarm moves with the infested creature causing them to have to make a Dexterity save every time they try to move to avoid falling prone, and reducing their walking speed by 1/2. An infested creature has Disadvantage on all ability checks and attack rolls while they are infested. The creature can spend its action to try and make a new DC 13 Dexterity save to escape the swarm.

Special ability: Creatures who are reduced to 0 hit points by the Pestilence Imps are not killed, and will stabilize and recover to 1 Hit point after 1 minute. However they are now infected, becoming a host to a new crop of Pestilence Imps. Each day the afflicted creature will grow a large painful abscess that will pop after 24 hours dealing 1 Necrotic damage. From the burst abscess a tiny Pestilence Imp is born. These newly born Pestilence imps generally skitters off, but may return to do "favors" for their parents like spoiling their milk or leaving them a piece of rotten food. Individual Pestilence Imps have 2 Hit Points, and bite for 1 Piercing damage.
