SFS Standard Adult Abysium Dragon Creature 13

Drawing on radiation as both a force of destruction and a source of energy, abysium dragons are tied to the radioactive starmetal of the same name. These dragons grow deposits of pure abysium in their bodies, becoming more radioactive as they age, causing aggression, agitation, and even loneliness since not many creatures can long survive the company of an aging abysium dragon. Abysium dragons frequently turn to pursuits such as augmentation and weapon crafting (to take advantage of their innate power source) and the construction of robots (to keep them company). This work drives abysium dragons to seek out sturdy, radiation-resistant materials they can use for crafting, and they often spend years at a time scouring small moons and asteroids in search of precious materials.

Abysium Maelstrom [one-action] (forcemagical) If the next action the dragon uses is Radiation Breath, the radiation becomes supercharged with arcane power.

Each creature that critically fails its save is also slowed 1 as long as it has this persistent force damage.

Any time an abysium dragon deals fire or poison damage, they can choose whether that damage is magical, and they can change any amount of the fire damage to poison (or any amount of poison damage to fire).
Draconic Frenzy [two-actions] The dragon makes two claw Strikes and one tail Strike in any order.
Draconic Momentum The dragon recharges their Radiation Breath whenever they score a critical hit with a Strike.
Radiation Breath [two-actions] (fireprimal) The dragon breathes a blast of caustic superheated gas that deals 7d6 fire damage and 3d12 persistent poison damage in a 40-foot cone (DC 33 basic Fortitude save). They can't use Radiation Breath again for 1d4 rounds.

All Creatures in "Dragon"

Dragon

All dragons across the galaxy are fierce, cunning, and strongly connected to magic. Many dragons, especially those who trace their lineage to pre-Gap worlds, are confined to the planets where they’re born and live their long lives without ever traveling to other worlds. Spacefaring people have had increasingly frequent encounters with creatures once known as “outer dragons,” those who can travel through the vastness of space. Now, most people simply call them “dragons,” though dragons who aren’t native to the planet they’re visiting (or invading) might be called “alien dragons” by the people contending with them. Whatever their origin, these alien dragons, like others who have existed for millennia, grow in size, strength, willpower, and magical might as they age.

Draconic Spellcasters

To make a dragon spellcaster, remove the dragon's Draconic Frenzy and draconic momentum abilities, and give them the spells outlined in their associated sidebar. You can swap out any number of these spells with others on a one-for-one basis. You might also increase the dragon's Intelligence, Wisdom, or Charisma modifier by 1 or 2 to reflect their mastery of magic.

Shape-Changing Dragons

Though it's uncommon, some dragons can take humanoid forms. They gain the following ability.
Change Shape [one-action] (concentrate, polymorph) The dragon takes on the appearance of any Small or Medium humanoid. This doesn't change their Speed or attack and damage bonuses with their Strikes but might change the damage type their Strikes deal (typically to bludgeoning).

Abysium Dragon Lairs

Any place with intense radiation— whether an abandoned nuclear reactor, a starship with a nuclear engine in meltdown, or a radioactive moon—is an attractive lair for an abysium dragon. They might also visit asteroids with raw abysium deposits or tremendous amounts of precious metal, slowly gathering the material to return it to their lair.
