Get Additional Training Points Through Training Tomes
In addition to gaining Companion training points from leveling and from completing a few side quests, you can find and buy Training Tomes to give you additional Companion training points. This allows you to train all your Companions closer to your own character’s level.
You can find training tomes in two ways:
You can purchase training tomes from professor NPCs in many taverns around the world. Take heed: they don’t let you buy more than 10 at any one time, and the price goes up as you level!
You can find training tomes hidden around the world. Keep an eye out! Once you find and use a training tome in the world, you can’t use it again.
