I have an PC who is a possible companion and I'd like for him to be able to train you in Energy Weapons. I'm sure a script of some sort and probably a package of some kind. Could someone either help me out or point me to a tutorial or example of some kind? Thank you.

How do you want this training to work? If it's just a question of asking the NPC for training, then a simple line of dialogue with a result script of 'player.modav energyweapons x', where x is the amount by which you wish to increase the skill, is all you would need.

Yeah that pretty much sums it up. Thanks a lot!
