With all of the characters at fandomhigh running around with special powers and abilities, we wanted to clarify things for those with "normal" characters, who have wondered about what kinds of abilities they can learn from others within the game.
The basic answer is, it depends on your canon, and on the canon that the powers/abilities are coming from. Any ability that requires an innate skill, or that a person is born with, or that comes from a mutation is off limits in most cases. But this doesn't mean that learning all abilities is off limits. For example, Rory Gilmore can certainly learn how to meditate - but she'll never be able to access the Force. (Woe!)
If your canon is highly reality-based, and there isn't much info on what kinds of special abilities your character could learn, keep the other canon involved in mind. For example, your character might not come from a canon where it's explicitly stated that they could learn how to block their thoughts from a telepath, but if the telepath comes from a canon where regular people can learn how to do that, then it's conceivable that your character could learn too.
The key here is the word learn. New skills shouldn't be something that the character can do automatically, and while the admins might not necessarily be watching for this sort of thing, it's something we want everyone to keep in mind. If you don't know whether or not your character could pick a skill up from someone else, ask them. OOC communication is love. If you want to do something that involves acquiring a new major skill or power for plotty reasons, but that might not necessarily be valid in your canon, e-mail the admins at fandomhighadmins at iambicnut dot com with your plot idea, and we'll see if it works.
