Default Languages: Infernal, Common, main language of region
Darkvision: You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern colour in darkness, only shades of grey.
Wings: You have a flight speed of 30ft. Your wingspan means that you can’t take off unless you have 15ft of empty space around you. When you take damage while flying, make a Constitution save with a DC equal to 10 or half the damage taken, whichever is higher. If you fail the saving throw, you fall to the ground. For levels 1-4, you can only glide instead of fly.
Daemonic Biology: You are Resistant to Fire damage, but Vulnerable to Radiant damage. You also get a Saving Throw against being Frightened and are immune to being Charmed by magical means.
Physical Perfection: Per long rest, you can use this ability up to your Proficiency modifier number of times. For any saving throw including death saves, you can use your Charisma modifier instead of the intended stat for the save.
Unencumbered: You cannot wear Medium or Heavy armour.
Seductive: You have proficiency in Persuasion or Deception, and when using these skills to seduce someone you can double your Proficiency bonus at the DM's discretion.
Under the Lash: You have proficiency with whips.
Devilish Disguise: At Lv.3, you gain 1 restricted spell slot and the spell Disguise Self. Unless the race is unisex you exclusively turn into a female of the race you choose. A creature can recognize your disguise by making a successful Wisdom (Insight) check.
Silver Tongue: If you spend one minute talking to someone who can understand what you say, you can make a Persuasion check contested by the creature's Insight check. If you or your companions are fighting the creature, your check automatically fails. If your check succeeds, the target is Charmed by you as long as it remains within 60 feet of you and for 5 minutes thereafter. If the target suffers any harm or receives a suicidal command, the effect ends. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to your Charm for the next twenty-four hours. You can have only one target Charmed at a time. If you charm another, the effect on the previous target ends.
