Osmosian

A mutation of a Baseform that allows absorption and use of non-living things. This includes two separate abilities:
 * The ability to absorb the inherent properties of inorganic matter (e.g. stone, metal, taydenite) and being able to cover yourself in it and shape the matter that covers you.
 * The ability to absorb, retain and discharge non-living energy.

Both abilities can cause mental instability when used for a long duration.

Mechanics
You can add and upgrade the Osmosian mutation to your baseform. Upgrading it means that you can store and use more energy without going insane. To turn into an Osmosian you have to spend 5 improvement points. Each increase in Osmosian control is 1 improvement point per level.

Hard Roleplaying
The upgrade to Osmosian comes with a safe storage of 5 Energy points. Each additional level adds 5 more points. As long as the stored energy is below the safe storage threshold, everything is fine. Once it is reached the insanity rulings come into play. At every 20% of capacity (this equals your Osmosian level) that you are over the threshold you must make a will resistance roll or succumb to insanity. The difficulty is equal to four times the number of passed thresholds (i.e. 4 at 20% over capacity, 8 at 40% over capacity, 12 at 60% over capacity and so on). Insanity comes with a disregard for other people and a hunger for more power. Until the energy is depleted completely, you will try to gain more energy at all costs and get rid of those in your way. Exceptions are possible and likely if the reason for absorbing a great amount of power was noble or not for the sake of power itself.

Lore
There was a lot of confusion on whether Osmosians were mutants or actually very humanoid aliens. This stems from the Rooters, a black ops group of the Plumbers, going rogue and using their resources to alter memories and create alien hybrids using the current leader of the Rooters, Proctor Levin, as a conduit to transfer the innate properties of aliens onto humans. By now, we know that the term Osmosian refers to any being that carries the Osmos gene which grants absorption powers.
