Arkanis the Ashbinder

Tiefling Traits

• Darkvision:
  Arkanis can see in darkness within 60 ft. as if it were dim light.

• Hellish Resistance:
  Arkanis has resistance to fire damage (already represented in his stat block).

• Infernal Legacy:
  Arkanis has innate spellcasting due to his Tiefling blood, though as a powerful Pyromancer he has transcended the usual limitations. His natural magic has fused into his spell list:

  • At-will: Thaumaturgy

  • 1/day each: Hellish Rebuke (cast at 3rd level), Darkness

• Ashborn Heritage (Variant, Optional):
  Since he's your big bad, you could give him a custom Tiefling trait like:
