Charisma (Stats Help)
Your charisma reflects how skilled you are in talking and convincing
others to your opinion. In The Two Towers, the primary use of this stat
is to affect shop prices, for both buying and selling. The higher your
charisma, the more money you will get from selling items, and the less
shopkeepers will charge you for buying some of their stock.
Charisma is also used when you attempt to tame a wild horse, so it
is of particular importance to riders.
