Supernaturally Dense Tissue - Like all inhabitants of her planet, Arina's body-tissue, skin, muscles, bones, etc. is extremely dense/solid, allowing her to withstand harmful strains on her body such as crushing weights, impacts, pressures, and changes in temperature. She also gains enhanced levels of strength and stamina, this is possible because of how hard her body has become, allowing her to resist tearing a muscle and/or her bones shattering easily.
Stellar Manipulation - Arina has the strong ability to wield the energy generated by stars, along with the electromagnetic, gravitational, and ethereal energies produced.This also includes the ability to turn stellar energy forces into tools, objects, weapons and other items, create semi-living constructs and/or create structures/buildings of varying permanence.
