You create a tiny mass of unstable blightburn crystal, allowing you to enhance the effect of a transmutation spell before the end of your next turn through a calibrated emission of blightburn radiation. The companion transmutation spell must be one that affects a living creature, is normally harmless, and uses a spell slot at least 1 level lower than your highest spell level. If you do not cast an appropriate transmutation spell by the end of your next turn, the unstable isotope becomes inert and disintegrates without effect.
If you use an appropriate companion spell before the end of your next turn, roll 1d20 and add your spellcasting ability modifier. The spell is enhanced as though your you had cast it using a spell slot 1 higher for a result of 10, 2 spell slots higher for a result of 15, 3 spell slots higher for a result of 20, and 4 spell slots higher for a result of 25 or more. If you roll a natural 1 on this check, the target of the companion spell is exposed to an overdose of blightburn radiation and must succeed on a Constitution saving throw or contract blightburn sickness.
Disease: Blightburn Sickness. A creature makes an initial Constitution saving throw to contract the disease (above) and any subsequent Constitution saving throws are at DC 20. At the end of its next long rest, a creature with this disease makes its saving throw or lowers its Constitution and Charisma scores by 1. A creature naturally fights off this disease by making 2 consecutive successful saving throws to resist it.
