Hellfire Tiefling (5e Race Variant)
From D&D Wiki
The tieflings of hellfire are said to a sagely sort. They are known to meditate while sitting on embers, taking advantage of their infernal ancestry's resistance to fire. The taming of their bodies this way yields a skill unique to them. Instead of using simple magics, they can manipulate their "inner fires" to burn opponents.
This race variant replaces the ASI and Infernal Legacy traits of the original tiefling race introduced in the PHB, later rewritten as the bloodline of Asmodeus.
