-|---- Knights of the Round Table ----|-

 As a Knight of the Round Table, there are certain standards
 which you must uphold.  To receive the benefits of your patron
 god, Yehovah, you must keep yourself in proper alignment with
 His ideals.  First and foremost, you must worship Adonai and
 no other.  Continuing this respect, you must always remain
 purehearted and honorable, lest you fall from His favor.
 Yehovah recognizes that unorthodox methods must sometimes
 be employed in order to forward the cause of righteousness,
 but He still requires that Knights stay away from the path
 of chaos.  Yehovah forbids the use or ingestion of any item
 sanctified to the legions of evil; such devices often feed
 upon their users, drawing them away from His path.

 To aid you in your neverending quest to extinguish the forces
 of evil, Yehovah grants you access to certain followers,
 equipment, and powers in order to sustain you during this
 struggle.  A list of these may be found under 'help powers'.

Followers

At 25th level Knights have access to followers, a warhorse, squire (who can be raised to a knight himself) and yeomen (who can be joined to guilds if they meet the requirements). Important for fast knights: trust your followers individually so you don't lose them when you're moving, you'll slow down to allow your little army to catch up with you, otherwise you'll outrun them and leave them behind.

Recommendations / Tips

As well as the required strength, dex and con it's recommended a Knight has a high charisma. This will affect many of the Knights powers, from leadership to invocation.

Lancelot trains Leadership to 270, spec 9. This will give you 16 Yeomen, 18 total followers when you include your Squire and War Horse.

A high perception is required for the skills related to being mounted. Like many guilds a balanced character is probably the best approach.
