Fifteenthborn - Empty Ones

An extremophile of the Borns. The Fifteenthborn have miraculously changed appearance over the ages always emulating the times in which they were born. Originally Fifteenthborn looked like an invading army of armored individuals. After they merged with civilizations it was realized they were merely suits of armor with some unseen entity holding it together. They experience pain and all range of sensual perceptions as any other Born. It is still unknown how exactly they breed however in organic partners their mixed blood comes in the shape of their organic partner and is seemingly birthed naturally just like any other race, with all the oddities than can potentially come of that of course. The Fifteenthborn always look like the style of armor in both the area of which they were born and most of the time the era as well. They can be modified and changed but requires care, their magical ability and caution. Pureblood

+1 Constitution, +1 Dexterity
Mastery of Form: A pureblood has a high capacity of ability with their own form. Empty ones absorb chosen material or a full set of armor to incorporate into themselves or entirely replace their old form. Taking on the properties of the new armor or potentially taking some of the feature of the absorbed armor, and in rarer cases improving the abilities of their armor they already have. They can only hold (Proficiency Modifier) armor but only one of their abilities if the armor had multiple. Changing potentially their size, shape, overall build and even what born they potentially look like the armor of. This mastery also allows them to add their proficiency modifier to their armor class. They can only an absorb armor or materials (Constitution Modifier or Dexterity Modifier) times every six days.
Body Begets Power: A pureblood can call upon the armor that they have absorbed. Any armor they are currently utilizing an ability for they can call upon it's Born shape. The pureblood can use one ability from the type of born the armor was made for following the exact rules of the ability. This ability can be used (Proficiency Modifier/2) times before needing a long rest to recover uses.

Halfblood

+1 Dexterity
Molding Mannerisms: A halfblood works nearly the exact same was as that of a pureblood however their appearance of what born they are can not be changed. The halfblood can add their proficiency modifier to their armor class. They can only absorb armor or materials (Proficiency Modifier) times per six days. The point of note however of their molding is that their armor absorbed can be used as a maximum of charges. A charge can be used to imitate their other halfblood ability or two to be used to imitate a power of the pureblood of their other born. Half of these uses can be recovered during a short rest or all for a long rest.
Quick Change: A halfblood has the fortunate ability to perhaps not change their appearance as fully but they can change their form much more freely. At the cost of an action and one hit die in damage the halfblood can change what their primary armor is. They get all of the abilities from their primary armor while only getting one ability from all other armors they have within them. This ability can be used (Constitution Modifier) times before needing a long rest.
