Swarm

Age. Your constituent organisms tend to have twice their normal life spans, but as long as you replace that die off, you are effectively immortal.   Alignment. Swarms have a complex relationship with morality, often seeing no particular reason to help others. This makes them neutral, at best, with a strong tendency towards being chaotic. Mortals of other races that have transformed into swarms of their own volition are almost universally evil.   Size. Though the size of your swarm oscillates some­what, you roughly remain as large as a human.   Telepathy. You can communicate via two-way telepa­thy with any creature that is within 30 feet of you if that creature knows at least one language.   Dissonance. You can use verbal components of spells, even if you do not speak, using the chittering, writhing, or buzzing sounds of your swarm as a substi­tute. You can be affected by silence and similar as usual.   Aberrant Nature. You have two creature types: humanoid and aberration. You can be affected by a game effect if it works on either of your creature types.   Reconstitute. When you take a short rest and would expend hit dice to heal, you can call to vermin of your type in the surrounding area to reconstruct your form. If you do, roll 1d4 - 1. During this short rest, you can maxi­mize the value of a number of hit dice of your choice equal to the result of this roll.   If there is a nearby dead humanoid or beast of Small size or larger for the duration of the rest, you can also consume their body as part of this ability. If you do so, roll 1d4 + 1 instead of the initial roll for this ability that you would otherwise make. Once you use this ability, you can't use it again until you take a long rest.   Amorphous Form. As an action on your turn, you can break apart into an amorphous swarm of your constituent creatures, dropping on the ground any items you were carrying or wearing. This amorphous form has resistance to bludgeoning, piercing, and slashing damage; can fit through a gap 1 inch in diameter, and otherwise uses your statistics.   While you are in an amorphous form, you cannot attack, cast spells, or use actions other than the Dash, Disen­gage, or Dodge actions, or taking an action to reform yourself into your regular shape. You can maintain this form for up to 1 minute, after which you take 1d10 psychic damage that cannot be reduced or ignored for each minute thereafter that you remain in amorphous form, as the constituent bodies of your form slowly assert their independence and break away. If you are reduced to 0 hit points while in amorphous form, you begin making death saving throws as usual. If you stabilize or regain hit points after being reduced to 0, you automatically reassume your normal form without any additional action. Once you use this ability, you require a short or long rest before you can use it again.   At 5th level, you can use this ability as a reaction if you drop to 0 hit points while in your regular form, as­suming your amorphous form and gaining a number of hit points equal to half your total character level, rounded down. If you use this ability as a reaction, you cannot use it again until you have taken a long rest.   Amorphous Talent. While you are in your amorphous form, you gain an additional ability, depending on the type of creatures that make up your body. Choose one of the following options:
Biting. You gain a bite attack as a natural weapon. This bite can add your choice of either your Strength or Dexterity on rolls to hit, and deals piercing damage equal to 1d6 + your choice of either your Strength or Dexterity modifier. You are able to use the Attack action to use this bite.
Burrowing. You gain a burrow speed equal to your movement speed. You cannot assume your normal form while burrowing.
Buzzing. YYour movement speed becomes 10 feet, but you gain a flying speed of 25 with the hover property.
Multitudinous. You gain temporary hit points equal to your Constitution modifier + your proficiency bonus.
Skittering. You cannot be the target of opportunity attacks.

Languages. You cannot speak, but you can under­stand, read, and write Common and one other language of your choice.
