Your Constitution score increases by 2, and your Wisdom score increases by 1.

As long as you are able to remain well fed, individual members of your colony will continue to replace themselves as quickly as they die. You have no maximum life-span, and show no recognizable signs of old age.

Myxapia have no predisposition towards any particular alignment, but can be mistaken for chaotic and even evil, as they fail to understand morality in the same way as other humanoids.

Mypaxia large enough to present humanlike intelligence are medium creatures. While it is possible for a colony to grow larger, such colonies generally split into multiple smaller organisms.

Your speed is 30 ft

Your body is malleable, allowing you to squeeze through gaps too small for other living creatures.  You can move through a space as narrow as 1 inch wide without squeezing, and are immune to the grappled condition. Equipment that would not fit through this gap would be left behind.

Your gelatinous body is far too soft to support most types of armor, but this plasmodic nature also makes you far more resilient against physical attacks. You cannot wear any armor, but are resistant to bludgeon, piercing, and slashing damage.

Myxapia are capable of exchange thoughts and memories on a cellular level. You can telepathically speak to any creature you are touching. They don't need to share a language to be heard.

Every cell of your body is it’s own organism, and each one has different duties. When reduced to 0 hit points you can choose to save the most important members of the colony. Leaving behind the bulk of your body, you become a tiny size ooze with a speed of 10 ft, hit points equal to 1 hit die + your Constitution modifier, and can only take the dash, hide, or dodge action on your turn.
