One ability score of your choice increases by 2, and one other ability score of your choice increases by 1 (which is typically indicative of your host corpse).

In the right conditions, a corpse inoculated with crystcelial spores can rise as a newly-formed, adult crystcelian in under a month. Crystcelians periodically redeploy their personal crystal spores to animate a new, fresher host if they don't maintain their current host's biological needs. Theoretically, a crystcelian can live on indefinitely, their minds and personalities changing with each rebirth.

You are a humanoid. You are also considered a plant for any prerequisite or effect that requires you to be a plant.

Crystcelians run the full gamut of humanoid species, from 2-foot-tall gnomes to 8-foot-tall golynns. Your height, weight, and size are determined by the species to which your host corpse belonged in life. It is typically Small or Medium.

Your base walking speed is dictated by the species to which your host corpse belonged in life. It is typically 25 or 30 feet.

You can speak, read, and write Common and one other language of your choice.

Your unique lifecycle allows you to co-opt some of the adaptations of your host corpse. Choose two adaptations from the species to which your host corpse belonged. The below is an incomplete list (GM's discretion.). If a trait is missing, get better at coding DnD Beyond and make your own damn copy. Or message me. I'm somewhat congenial.

• Damage Resistance. You have resistance to one damage type determined by your host body’s species.
• Darkvision. The darkened chambers of The Low are your home. You have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern colour in darkness, only shades of grey.
• Muscle Memory. You gain proficiency in one skill of your choice. You can take this option multiple times.
• Natural Weapon. You have a physical characteristic, such as horns, claws, or teeth, that acts as a natural melee weapon which you can use to make unarmed strikes. If you hit with it, you deal bludgeoning, piercing, or slashing damage (depending on the body part) equal to your Strength modifier plus a damage die determined by your host body’s species, instead of the bludgeoning damage normal for an unarmed strike.
• Powerful Build. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

When you die within 100 feet of a humanoid corpse that has been dead no longer than 24 hours, and that hasn’t been subjected to magic that accelerates decay or prevents decay (such as the gentle repose spell), you can use your dying breath to eject crystal spores to inhabit that corpse. Roll percentile dice. If you roll a number equal to or higher than the distance between your body and the corpse in feet, your spores take hold. For example, a target 30 feet away requires a roll of 30 or higher to succeed.

On a success, the new body rises again in 2d6 days. You gain the benefits of a long rest and lose your previous Symbiotic Assimilation adaptations, gaining new ones according to the species of the target corpse. On a failure, you die as normal.

The unique collaboration of mineral-hyphae within your body generates a very specific resonation - one that is discernible only by other creatures with a similar network coursing through their body. This resonance can be used to locate your kin, and to communicate with them. The range of this ability is dependent on your level, as shown by the table below.

You may reanimate a humanoid corpse that has been dead for no longer than 24 hours by infusing it with mineral-hyphae from your own body, turning it into an extension of yourself. You can cast Animate Dead once per day without using materials. If you cast it on a different target than your current servant, your current servant perishes.

The servant uses the Zombie statlock, with the following modifications:

• It is a plant, in addition to its other creature types.
• The range of the effects from your Resonance ability are doubled on it.
• As an action, if your servant is within range of your Resonance telepathy when you initiate this action, you can you can perceive through your servant's senses and control their actions as long as you remain on the same plane of existence. Additionally, while perceiving through your servant's senses, you can also speak through your servant in your own voice, even if your servant is normally incapable of speech or does not know the language. While doing so, you are Paralyzed.
  
  You must still use the statistics and abilities of your servant.
