Follower Got Whimpy On You?
*Part 1- Check Follower Stats- (
http://www.gamefaqs.com/boards/615805-/61216136) Pull up the Console (~). Click on the Follower. The Follower's ID should appear on the screen. In the Console type "getavinfo <actor value>" (without quotes). This will give you a readout of the Follower's stats. Examples of what values to check would be "getavinfo health" or "getavinfo stamina". To check other values, here is a (

*Part 2- Update Follower Stats When a Follower is picked up early in the game, the idea is that as you gain xp, so do they. Not quite. I'm not an expert on the mechanics within the game, but they will lag in stats as compared to you. If you have become attached to a follower and wish to continue to use him or her after he or she has become obsolete, you can upgrade them! Using this method, my current Follower, Lydia started with a Stamina of 74 and Health of 181. After completion of the procedure, her Stamina jumped to 114, and her Health to 321. See this (
http://www.uesp.net/wiki/Skyrim:Followers#Follower_Stats) UESP.net Follower Stats article.
A warning! This method strips the Follower of any items you have given them! Strip them of all upgraded items, then follow the procedure, unless you don't care about losing them.
The Procedure: Update his or her stats by dismissing the companion, then opening the console, clicking the Follower in question (the Follower's ID will appear on the screen), typing "disable" and then typing "enable" without the quotation marks, closing the console, then ask them to rejoin. His or her stats will all be updated to match the player's current level.
Remove Stolen Tag from Items (
http://www.uesp.net/wiki/Skyrim:Console) Source: UESP.Net Console Article. This has been added to the cheat section because, no doubt it is a cheat. However there is an in-game glitch where items that I have purchased and given to my follower to hold, or items I have removed from others after defeating them in combat sometimes are labeled as stolen. I'm not sure exactly what the mechanism is, but I know I am not steeling items. So if you are a cheater or a victim, here is how you remove the "Stolen" tag from gear. Simply drop the item on the ground, open the console (~), click on the item (its ID should appear onscreen), and type the command "setownership" (no quotes). It can be difficult to select certain items. You might have to toggle off the console (~), and change the camera angle. If the displayed ID code does not begin with "ff", you have not selected an item, but rather an object in the world (ground texture, light, container, etc.).
