Comments from the Finger: Our patrons chose Dark Matter, our very own sci-fi setting, for an upcoming book, and we're working really deliriously hard on it. Here's the first subclass I wrote for it.
(Also, All Hail the Glow Cloud.)
The depths of space hold terrible forces that can warp and twist a man irreparably. Radiation, for example, normally offers a cruel, agonizing death, but can sometimes fundamentally alter those subjected to its strange energies. Those which emerge from this process alive are deemed “radiation freaks” for the horrible physical deformities that accompany their transformation, but some are changed in even stranger ways. Radiation has the potential to alter a creature at the magical level as well, resulting in mutated sorcerers wielding horrific power.
Starting at 1st level, your body is saturated with harmful residual radiation. You can use your action to activate or suppress a radioactive aura. While active, your body glows with a bright light in a 10-foot radius and dim light for an additional 10 feet. Additionally, each creature which comes within 5 feet of you or ends its turn in that area takes 1d6 radiant damage. At 6th level, this damage increases to 1d8 and at 14th level this damage increases to 1d10.
At 1st level, whenever you deal cold, fire, lightning, or poison damage, you can replace the damage type with radiant damage.
By 6th level, the tumors within your body can of rapidly shift your magical metabolism. Immediately after you take damage, you can use your reaction and spend 1 sorcery point to gain resistance to that damage type until you take a short or long rest, or until you use this ability again.
Starting at 14th level, you can use your action to transform your entire body, along with everything you’re wearing and carrying, into a cloud of dangerous radioactive material. This effect acts as the gaseous form spell, with the following differences:
- Your flying speed is equal to half your movement speed.
- If another creature enters your space or ends its turn there, it takes 2d10 radiant damage.
- You can cast cantrips while you’re in this form.
At 18th level, you can spend 3 sorcery points to bombard a creature you touch with a near lethal amount of radioactivity. At the beginning of that creature's next three turns, it makes a Constitution saving throw against your spell save DC. On a failed save, the creature is poisoned for up to 1 hour and takes 6d10 radiant damage.
The creature can reattempt this saving throw at the end of its subsequent turns, ending the effect after three successes and taking 2d10 radiant damage on a failed save. These successes need not be on consecutive turns. If the creature fails this saving throw three times, it remains poisoned for the entire hour and takes 1d10 radiant damage at the end of each of its turns.
