Celestial. Star-like properties at cellular level, usually at the cost of metabolism.
Illumination (minimal) - Your body can produce light at will, at the expense of metabolism. This provides the ability to produce minimal illumination, barely enough for reading in the dark.
Anti-Glare Vision - No amount of light can blind you anymore. You’re not going to need sunglasses or welding glasses anymore. Unless for fashion purposes.
Illumination (substantial) - Your body can produce light at will, at the expense of metabolism. This provides substantial lighting, enough to make you a beacon to monsters, or, for example, comfortable navigation in the dark.
Increased Tissue Density - Your tissue composition has become substantially more dense and solid. Your body weighs more and you gain considerable resistance against cutting damage, but you also require more energy to move, increasing metabolism and stamina consumption while moving. On the upside, you can still receive injections from standard steel needles.
Increased Bone Density - Your bones cannot break anymore, not by any normal means. But you become heavier, and require more sustenance. Your body also needs more calcium from diet.
Dulled State - All your senses with the exception of vision are dulled. You are more resistant to pain but also more resistant to negative and positive morale modifiers.
Solar Flare - You can expel hot plasma from your fingertips at the cost of hydration, causing massive burn damage to anything the plasma hits. Activating this power will also automatically destroy any handwear you might have equipped, so try not to wear gloves or watches, or at least remove them first.
Universal Matter Absorption - Your body can absorb 500g of any material per day to recover hunger, equivalent of a moderate meal. The absorption takes place through skin so you don’t have to chew rocks or anything - just hold a rock (or whatever) in your hand and activate this ability.
Fusion Metabolism - A small fraction of your cells have been transformed and they now employ fusion reaction to produce energy. This greatly increases your resistance against cold and grants you extra strength, but your metabolism is slightly faster.
Quasar - Occasionally random parts of your body produce an intense flash of light. The more covered your body is, the less likely this is to show on the outside. Partial body coverage reduces the flash visibility as well.
Illumination (extreme) - Your body can produce light at will, at the expense of metabolism. This ability is enough to temporarily blind monsters and NPCs at the expense of substantial metabolism and also stamina. Use sparingly.
Black Hole Stress - The more in pain you are, the more violently loose objects start to move around you, causing havoc, but at least they never hit you directly.
Black Hole Darkness - Your body absorbs light, making your immediate surroundings permanently dark. Darkness follows you wherever you go. This is exceptionally disturbing to NPCs.
Black Hole Disintegration - You can pulverize any creature, item or tile with your touch. This action consumes a substantial amount of your focus, metabolism, thirst, fatigue and tiredness. Use sparingly.
Omnivision - Your eyes can see almost any wavelength. You can perceive radiowaves, the ultraviolet, microwaves, gravitational waves, the infrared… you name it, you see it. Nothing can hide from your eyes. You automatically map several levels beneath (or above) your feet, as well as can see any monsters there. On the downside, closing your eyes is basically pointless now as you can see through them.
Neutralized Quasar - This is the next step of the Quasar mutation, nullifying its effect. No more waking up in the middle of the night just because your face flashed like a camera.
