Malleable Bio-Mercury Form

Composed of a non-toxic liquid mercury. Their form allows them to alter their shape by collapsing into a featureless mass, extending blades from their skin, or molding themself into different forms. The ability to shape-shift extends to the most basic of rudimentary weapons. The liquid mercury form is non-organic.

Techniques
Anyone whom uses this ability will have all the abilities also, written below:
 * Self-Sustenance: is no longer a carbon-based life form and does not eat or breathe the same way as normal humans. Still, they sometimes consume food out of habit and sometimes have not realized the scope of her change.
 * Molecular Adhesion: gives them the ability to cling to solid surfaces and move their body at will even without overt locomotive features.
 * Enhanced Durability: skin, bone and muscle transformed into liquid mercury to make it stronger and harder than human; impervious to injury to a certain extent.
 * Magical Resistance: very hard to magically detect or influence due to their non-organic form.
