I am wearing Fungus , results may vary

Some armour "tags" for non conventional armours

Not Really Magically Armour Tags:

Climbing Aid: Has hooks, spurs , claws or helpful rope hoops to aid in climbing

 Non-ferrous metal: This armour is made from metals that are not ferrous so if the g.m tries it on with magnets or electrical attacks that ignore metal a.c you can be like nuh-uh non ferrous metal. Examples Um some kind of bullshit fantasy titanium or something.

Buoyant: It floats! Possibly too well. Examples coconut husk (see links at end of post, I suspect though that would sink), reeds, packed with kapok or some other plant fibre, bamboo, mushroom caps

Noisy: Ceremonial bells and clappers and chimes. Makes a lot of noise. Might be terrifying to a particular kind of spirits. Also lets animals know you coming a mile off so you are less likely to startle a bear or a snake or something.

examples: ring mail with little charms and bells attached, a internalized bag pipe system (also Buoyant!), layers of extraneous loose plating like scales, rings similar to those attached to a Buddhists monks staff (for warning away animals and to alert people within ear shot that there was a monk nearby for all your monk needs)

Custom: It's made just for you, so it penalizes other people wearing it , and when ever the g.m tries to be "that would be uncomfortable in armour" you have a reasonable amount of wiggle room to go "nah I'm sleeping in my armour anyway"

example: expert craft work, a clone of your own skin grown harvested and tanned, luke warm wax that is poured over you and hardens but remains soft at the joints, it's assembled by ants or homunculus on you.

Insulated: It counts as cold weather clothing. Examples untreated seal or walrus hide like just roped to your body, thick furs, sacks of hot ash (sending up blinding clouds when penetrated ), penguins, congealed fat coated cloth

Intimidating: it makes you look big and scary. Morale check for dumb things.

examples; big ass horns adorned with burning pitch , skull masks, ludicrous spikes, helmets that disguise and/or amplify your voice, mummy bandages or other monster disguises

Subtle: it's not that noticeable and can be worn under clothing or gives the appearance of clothing

Examples: fine chainmail, stylish black leather, reinforced great coat , dress reinforced with steel banding

Don't Touch Me: It is spiked , anointed in caustic paste, sharpened , barbed ,hooked , foul tasting or smelling or otherwise trouble .  Grappling or eating you cause pain or at the very least discomfort

Examples: barbs , hooks , etc, obsidian scales, covered in chili oil, thorns/insect stings attached with tar or sap, toad skin armour, hedgehog skin armour

Magical Armour Tags:

Ablative : this armour is designed to break away absorbing damage, either with a fixed pool of damage reduction (absorbs 2 points of damage until it has absorbed 12 points) or a "Shield must be Splintered" system. (you may sacrifice the armour to reduce damage from a blow to a single point)

Examples: A potion that makes you bleed  from skin , and then hardens into a thick scab crust, layers material frozen on you,  stitched together vermin , semi-real illusions or alternate reality armours

Possible non-magical examples pumice stone , quilted paper , cloth 

ehh. It not so bad ?

Share holder Parasite : This armour has a store of hit points that you can replace your own with when wounded. The percentage of hit points you have replaced as compared to your own however is its chance of making you do what it whats you to do. Once hit points have been replaced they are replaced for good. 

 Examples
Ground up Golem: this armour has an interior space filled with sand. Heavy but very good at absorbing force. The sand leaks out and replaces your spilled blood until you are replaced with maddened elemental spirit. 

Fungus: Starts inserting itself in your organs and blood supply . At some stage will want to convert your whole body to a fruiting body and get you to climb stuff and release spores.
Ancestral armour: empowered by cantankerous committee of ancestor spirits. Possible unaware, possibly just uncaring that the current wearer of the armour is not their descendant. Because they are going shove your soul straight out of your body, you good for nothing gadabout!

Workaday Parasite: the magic properties of this armour are powered by your life force. It skims the first 3 hit points of any healing you receive but this armour cannot be disenchanted like a standard magic armour.

examples: Transparent glass , inserts needles into you and fills itself with your blood

A tangled mat of leeches, armour hide that grows into you and has to be cut lose to be removed (troll skin)

Space Warping: Using magic principle as those involved in creation of portable holes, bag of holding and carpets of entrapment, missiles pentrate this armour but fail to ever reach the flesh on the other side , mere fabric millimeters away.
It has a limit to how much it can absorb though. At which point it releases all the missles outward from the wearer in a fearsome torrent of pointy shit.
Variant 1: as above but each missile is not stored but redirected and released 1d10 rounds/minutes/hours later
Variant 2: the interior distance of the fabric is greatly stretched but the missle will still make it through, but a hour later. Wearer is advised to not be wearing it then. Or turn it inside out before hand.

Anointed: armour is not ignored by ghostly hand touch attacks or stuff that just has to touch "you" but not your skin exactly, for the magic to work.

Examples: woven witch hair, mosaics , inscriptions , mummy bandages, calligraphy (on the armour or attached paper) , ghosts or protective spirits incorparated into the armour, talismans in the form of teeth , bone, skin or gems.


Secretions: the armour secretes a fluid or oil. This might make it silent, slippery , fire resistant , highly flammable , insulated (cold or electricity) or just gross.

Examples: decorative spouter gargoyle heads as  pauldron , drowned perpetually wet haunted armour, polyps oozing away merrily , algae clots , symbiotic ooze or giant protozoon . Xenophyophore ? or an oversized Foraminifera?

Hive: insects live in the armour, either through specialized compartments or incorporating the hive in the armour. They may be capable of repairing the armour or just sting and bite the shit out of your enemies. This could be non magical if you were somehow secreting the pheromones that would make the hive believe you to be their queen,

examples: ants, bees , wasps. Little naked versions of you. Flies in a semi rotting organic armour. Fur with charmed fleas that infest and bedevil your foes 

Sustaining : the armour is capable of giving you food , water or air.

examples: symbiotic algae, plant or fungus which converts sunlight , or your own detritus into substances. Still suits from dune. Biotech. Bonded Air elemental. 

Weaponized: has built in or concealed weapons, or weapon potential. Maybe melee or missile, only suitable as a back up or actually formidable enough to rely on.
Examples include coconut husk weave with trimmings of animate rope with sharks teeth as for a chain saw like effect  or extend as a whip like radula .
Judge Dread/Death (skeletal) eagle pauldron that can be commanded to strike as a heavy crossbow. Quills .
 Hatchet head helm. Nematocysts (possibly ranged), seed pods or acidic spore blasts. Concealed chains or spine with snapping skull. Animal skull gauntlets . Sashimono that converts to a spear or stave.
