Faendal

"Riverwood is okay I suppose... for a Nord village." - Faendal Faendal is a Bosmer archer in Riverwood. He and Sven have a rivalry for the love of a local girl, Camilla Valerius. He offers Archery lessons at the Adept level.

Interactions
Faendal is a potential follower if the Dragonborn sides with him by exposing Sven's letter to Camilla or by giving Camilla his own fake letter. Faendal is able to join The Blades.

Archery
After taking Faendal on as a companion, it is possible to receive free Archery training. (Confirmed on all platforms) Purchase the next training level up from Faendal, then speak with him to open the trade option. Take back the money paid for training. This can be repeated up to five times per level (Up to level 50 in archery).

Pickpocket
With any trainer, use the cutpurse perk to pickpocket the money back. The total value of gold affects the success rate.

Another way to steal large sum of money from a trainer is to pickpocket them, put a paralyse potion inside his inventory ( which obviously needs a specific alchemy perk) and when he is paralysed wait on sneak mode. As soon as the paralyse effect runs out you can pickpocket the gold without him noticing. I reached level 90 in speech this way by doing this tactic on speech trainer in bard colledge.

Lockpicking
Faendal's house has an Apprentice level lock. To raise lockpicking, the key to his house will need to be returned, if it was taken. With Faendal sure he is following, pick the lock to his house, then go back outside. He will lock it again - resetting it to be picked again.

Faendal's House
Faendal's House is located in Riverwood. Sometimes Faendal will not leave his house, leaving the door in an unlocked state. To fix this, reenter and try again.
