Mineral Skin

 Talc skin, is the softness she is able to muster, she is able to mark up surfaces with her finger tip as if drawing with chalk But this is also a form not ideal for combat. Because chalk/ talcum powder is extremely soft and easy to shatter. If she is hit while in this form by a blow she is down for the count.
 That makes her skin a pale, ghostly white.

Gypsum , No real use for this one. This will turn her skin into a slightly darker gray.
Calcite skin, a slightly harder skin then Gypsum, this skin is good for acid neutralization. Aka, it's good in certain situations that might involve acid or acidic toxins. This one ranges at a 3 on the hardness. This makes her skin tone shine a bit, with an off white sheen to it.

Fluorite, this skin is a 4 on the hardness and comes with the ability that lets Fan be a literal walking lantern. She gives off an illumination that allows her to be perfect as a guide. This layer is where it becomes a bit harder to break, and covering her fist would certainly cause injury to a person. SMACK POW! Right in the kisser! This one makes her skin an off green. And more so when she is in the dark.

Apatite skin, is level 5, much harder than the previous this one is ideal for the attack. Causing more pain to those hit by a blow. Her skin can still be broken through if she is not careful. This turns her skin into almost a crystalline type appearance. Slightly translucent.

Orthoclase skin, harder than the previous skins but takes more effort to keep up. Ideal for attack and shielding. It is a 6 on the hardness scale. Turning her skin to a cloudy yellow hue.

Quartz skin, level six, it follows the same pattern, turning her skin to a cloudy pink hue as if she was made of marble.

Topaz skin, now we are getting to the fine gemstones. This is a level 8 of the last three. This turns her skin to a translucent faint purple. It's one of the hardest to crack, and is perfect for defense and offense, however, takes more energy out of her to use.

Sapphire Skin- This is level 9 and comes in either blue or red, this is the second hardest for her to maintain, only lasting for extremely short spurts. Ideal for quick attacks or defensive maneuvers on the spot.

Diamond skin This is the hardest substance known to man. Diamond. This one will burn her out. She is can only use this one in short spurts and using it early on will cause her to be left weakened. Ideal for a last resort blow, it does come at the cost of her energy. Can only be used once in combat  and acts more as a trump card last resort.
