Can I refund a perk point?

While leveling in Skyrim I put a perk in a tree, but now I feel like it is wasted, since I've found blowing things up with spells is much more fun than stabbing things with a giant sword.

Is there anyway for me to recover the wasted perk? I'm on the PC so I was guessing console commands could help.

If you are on PC, you can use the console to add and remove perks.

Finding a perk id:
help [name of perk] 4
help Armsman 4

Removing a perk
player.removeperk [perk id]
player.removeperk 00079342

Adding a perk
player.addperk [perk id]
player.addperk 00079342

Notes:

• You can use the PageUp/PageDown keys to scroll the console.
• Use double quotes when searching for a perk with a space: "Steel Smithing" -yx
• The UESP has the perk id for all the skills. -Mark Trapp

You can remove perks you currently have by using:

player.removeperk perkid

To find out the id of the perk, type this in:

help "perk name here" 0

This will bring up a list of all items matching your query (hopefully it contains the perk in that list).

To add a perk:

player.addperk perkid

Note: for perks that have multiple levels, you will have to remove all the perks for those skills to clear it out. i.e. one handed has 5 levels, the way skyrim tracks that is to add a perk for each level, so there are 5 different perks for one handed.

To redistribute your stats, you can use:

player.setav stat value

However this will not persist across saves, to do that use:

player.modav stat amount_to_modify_by

That can be used to set all skills and stats.

There is no way to reset your perks on the Xbox 360 without the Dragonborn DLC, and no way to do it on the PlayStation 3 until Bethesda releases Dragonborn for that console, but you can redo your perks in the PC version of the game by using the console commands:

player.removeperk <perk ID>
player.addperk <perk ID>

Where <perk ID> is replaced with the code for the perk you want to change. The UESP Wiki contains a list of these codes.

Careful with these: they have been reports that they will brand you a cheater and prevent you from gaining any achievements, but this is disputed.
