Lives on the life-force of the wearer and harvests (1d4)/2 HP (rounded up) per level of the wearer AFTER they have recovered HP from each long rest.
Wear gets: Resistance to Frightened, Resistance to Fatigue/Exhaustion, Resistance to Poisoning
For each 12 hours the armor is not worn the wearer must make a DC25 Con or take 2 levels of exhaustion (1 level if they make the save) and are at disadvantage on all actions for the next 12 hours (shaking, sweating, irritable, unable to concentrate) and have a -1 Con. After three successful saves (without putting the armor back on) the wearer has weaned themselves from the armor and will not feel any need to wear the armor again. The -1 Con is permanent, however.

Sleek, black plate with a chitinous appearance. Slowly sizes itself to fit the wearer over the course of two days and fits like a custom made glove thereafter. While wearing the armor/parasite the wearer feels extremely confident and energetic and aggressive and sees tangible benefits to strength and dexerity. The armor feeds on the life force of the individual and is highly invested in keeping it's host alive. The armor has animal cunning but not sentience and doesn't understand spoken languages. The wearer will find excuses to keep wearing the armor and will feel uncomfortable when not wearing it. This will become full-on withdrawal after 12 hours.


That's intresting and is also more along the lines of a cursed item rather then either a playable race or a monster
