PlayerData.lua contains a host of variables and functions related to data that is stored in the Save game.
PlayerData
The Following Properties are accessible through tes3.player.data.KBProgression.* (ex. tes3.player.data.KBProgression.xp will return the Players current Experience total) You should not write directly to this table, doing so could potentially break features of the mod:

• .xp - returns the players current total xp
• .xpReq - OBSOLETE Abandoned property from early in development. Not present in 1.1.7 onwards. use playerData.calcXPReq() to get the player's xp requirement
• .levelPoints - Table of the players attribute, skill and perk points
  

• .perks - a table of all perks the player has acquired. Uses perkID as a key and stores a boolean value. Don't use this to add/remove perks, use the functions listed further down
• .activatedPerks - a table of all perks that are activated on the player. Similar to with .perks, you shouldn't write directly to this table
• .incPoints - table of additive skill point bonuses. The values here are added to the levelPoints table every time the player levels up. uses the same keys as levelPoints
• .pntMult - a table of attribute/skill/perk point multipliers. these values are multiplied by the MCM defined points per interval settings when determining how many points you gain at level up. Defaults to 1, but can be modified by scripts. uses the same keys as levelPoints
