Sigil: City of Doors

Must half fiends have wings or tails? I noted in the creator they get the feat 'Wings' which gives a bonus to movement rate but their description says that those are not always a facet of the race, merely a suggestion. On making one to test it I found I was prompted for getting them by the Styx Oarsman. Are they obligatory? If not, how can one still fix the skin tone to that of the chosen shade?

Someone else (who has played the current race) will have to answer this question. I'm just chiming in to mention that half-fiend and half-celestial are on my list to rework as template classes at some point soon.

I am fairly certain there is (or was) an option to get them removed, as well as an option to just get one or the other?

you can ask for the tail to be removed but not the wings. so your skin tone might fix if you ask for the tail and then remove it again. I have two half fiends that do not have their wings , their skin tone is fine. One dosnet have the tail.

Thank you Lucadia. That is very helpful!

After testing this I found that the tail was not added and though I was told I would be booted to make the addition, I was not. Body skin tone (hands and feet) remain creator static as the most pale. Should I post this in the bugs forum?

Iirc in 3ed, half-fiends got wings 50% of the time.

And it's a buggy issue anyway, since certain fiendish characters (not mentioning names) have no wings and still get the movement speed increase. Adding only the tail doesn't fix the tint issue. You have to go hardcore and get all of it to fix the tinting. As for having a tail, I don't think half-breeds get them, so the oarsman won't give you one.
Incubi and Tieflings I know can get them, though.
