Your pyrokinesis has evolved, granting you power over fire and flame rather than just cinders and ash, and you can now regenerate using fire instead of just cinders and ashes. All of the things that you make out of cinders and ash are capable of withstanding ten times the force that they previously could.
In addition to this, your burning core has also evolved, becoming so dense and hot that it could be considered a miniature sun. It has also become durable enough to withstand a nuclear bomb.
Alongside this, you can temporarily or permanently gift someone pyrokinesis focused around either cinders, ash, or fire, though this will temporarily weaken you by one ninth for a lunar cycle per individual you give powers to.
