Borderlands 2: How to Reset Your Skills
So you started purchasing the skills for your character, and then later realized.. ehh, the skills I chose kind of suck, but where’s the damn reset button?
Well, you’re in luck, because it’s out there, but you won’t find it in the menu anywhere.
What you need to find is the Quick Change machine, which happens to also have the skill reset feature.
If you haven’t used the appearance vending machine, it’s the machine with the male / female symbol on the front of it (you know, like the signs in front of public restrooms).
You can find one right outside the building with the fast travel box in Sanctuary, as well as randomly scattered throughout the rest of the world as well.
On the minimap, the icon looks like the top half of a person.
