Spoiler Question About Wyll

[Chaosolous]

If he gets turned into a Demon/Devil whatever it is, how come he doesn't get DarkVision and when you look at his Character Sheet it still says Human.

I thought he wasn't human no more.

Is there a spoiler ending for him that I don't know and he's secretly just under the illusion of being a devil or something? I mean, bro got the look but not the abilities?

[Damphair]

I think he's still mostly human, not fully devil. You can also get darkvision from his warlock talents.

[Glyph]

He just gets a cursed appearance because his patron is petty.
