I decided to try and create a respec potion mod without the SKSE yesterday and failed. I thought I'd share what I've learned and post the code I tried to use in the hopes that maybe it will be useful to someone else.

I quickly learned that you can't directly access perk points, I also learned that you can't directly de-level a player either. Both of these things screwed with my attempt at a workaround.

The following code is designed to:

• Set all player skills to their default
  
• Remove all player perks
  
• Set all player stats to their default
  
• Set the player's level to 1 (Can't be done as far as I can tell without using the in game console)
  
• Re-level the skills back to what they were

At step 5 I assumed this would bump them back up to their original level however my tests gave different results. My level 35 Khajiit archer character when reset to level 1 with the console only leveled back up to 7 when using this script

Anyway I hope this will be of use to someone, here's the script: (Sorry about the indenting, in copying one level of indentation seems to have been lost)

I think that is because you can't wipe out all the old XP that was earned. The fXPLevelBase and fXPLevelMult were continuing to compound the total XP needed to make the next level without being reset. I've been trying to hack leveling for weeks.
Bugthesda indeed.
