I'm playing a Tiefling Witch and taking the Disguise hex. I already warned my DM that things could get a little strange at times, because of my character being an Outsider. But just how strange?
I'm not taking the hex to do things like this (mostly I'll pass for Human as an Aasimar), but it's interesting to consider. Here are some possibilities:
Invisible Stalker. Unfortunately their Natural Invisibility is an ability which I would not get, but still, a nebulous humanoid-shaped cloud? That's a little odd. There are some other wispy Outsiders as well.
Chaos Beast. A bizarre choice; a constantly shifting mass of tentacles and who knows what-all. Surely that could be useful in certain situations.
Animate Dream. I would expect to have the most trouble with this one, if any. They appear differently to everyone, as something from a personal nightmare.
Basically, I'm curious about what other people would do or have done, either as a character in similar circumstances, or as a DM dealing with it.
