In most apocalyptic settings(specially those with a zombie-kind of plague) the main character(s) only have very mundane means to deal with their problems and those always have a catch: any gun they use has a limited supply of ammo, their sharp objects get dull after a while or they break like any other object used as weapon for too long.
And don't even start with the basics like gathering food, medicine, finding or building somewhere safe to live, hygienic necessities and etc.
I want to create an apocalyptic(or post-apocalyptic in this case) setting where some characters actually have something akin to paranormal/supernatural powers, but here is the crux of my problem:
1. Which kind of powers could work well in a "realistic as possible" scenario like this?They can be either scientific or more fantasy-like but must sound/seem realistic.
2. How can I give them powers that are useful but not enough to make them seem like an overpowered character? Because I want them to have an edge, but not enough that they can only rely on their powers.
