A plasma contaminated species that have for all intents and purposes died and through the medical and scientific experimentation with solid and liquid Plasma, resulting in the death of many test subjects when used for medical application, But days after these considered failures, the subjects revived much to the shock of the researchers and medical staff, Medical staff examining them proclaimed them deceased still, with incredibly high levels of phoron in their systems and partial decay had settled in, affecting their bodies in a new way, while preserving their decease organs their brains suffered from the damage of their death reduced their mental facilities, and in some a loss of memory entirely, Their bodies stuck in the inbetween of decay and living their movement swere declared as 'slow but not Diona slow'
Pros:
Higher brute resistance
No pain (But possibly messages that generate "You've been hit" when struck
no toxin damage
No oxy damage
(The higher brute resistence and no oxy loss won't mean you will be able to tank space since your bones will still break and it will still kill you)
Cons:
Only move abit faster than diona
Very weak to fire and burn damage
Going too long for food turns speech into gibberish as food sustains your brain functions
Neutrals
A possibly bite function that, does only three brute but when done on a aggresive grab living mob/player gives them abit of nutrition and with how quickly you would recover from such a low amount of damage you couldn't kill someone with it
Going too hungry for too long could give you bacl "You hunger" messages
They have a dark purple blood that could be flammable due to the phoron in it but wouldn't be airborn or burn for long so it won't be used for griefing
Losing limbs could let you simply reattach them by burning them on with a welder or cautery, but when lost will have a message "The decay has set in" so other players couldn't use it but maybe you could?}
This species could be used by players for making a undead esque race, either for the RP and unique characters, or those with a different taste for things
This is all just conjecture,id eas ive put together and will add and remove things as this goes along
