Heya. I have 2 rogues in my party. I have yet to find a guild where I can switch roles. I've tried ever guild in the first two towns. Where, and when can my rogues switch roles? Thanks.

They can join the Thieve's guild in Ishad N'ha (the windmill building) and ascend there.
Also, one can become an Assassin (or anyone for that matter) by completing a quest for Scanthril the rat guy at the burned out house.

it would be handy if your rogues are between 13th and 14th levels...

heya man,
you can have as many assasins as you want (even 6 !!!).You only have to enter thieves guild in the third town with the character that carries Scanthril's assasin dagger.Wait until the guild master tells you that you have an assasin dagger then open inventory and move the dagger to another character.That's it.
With your assasins try to learn kung fu as much as possible.eventually you will learn lethal fist ( which can instantly kill a monster !) and backstab.Try to fight hidden in shadows and you will do extra damage.Wanna see your assasins delivering 30 or more damage empty handed ?

Why's that Adam?

you can squeeze more training and hit points in
