Feral Tiefling

Feral tieflings are faster, more ferocious than their more civilized counterparts. Their demonic features are more pronounced, and their horns never stop growing. Their fingers end in brutal claws, and their eyes are a solid color with no pupil. It is not uncommon to find one with wings.
These tieflings are often found in mountainous regions away from civilization, traveling in packs or alone.
You choose Option 1, Option 2, or both Options 1 & 2 as follows:
You can replace the Tiefling's Ability Score Increase trait (+2 to Charisma and +1 to Intelligence) with the Feral trait (+2 to Dexterity and +1 to Intelligence). You can replace the Tiefling's Infernal Legacy trait with 1 of the following 3 sub-options:
a. Devil's Tongue, which changes all the racial cantrips and spells gained.
b. Hellfire, which changes one of the racial spells gained but keeps the others unchanged. (This technically modifies Infernal Legacy rather than replacing it entirely, but for simplicity I'm going to phrase it as a partial replacement.)
c. Winged, which grants a flying speed.
There are a total of 8 combinations available above depending on which options and sub-options you choose (including the standard Tiefling if you pick neither option).
