I'm nearing level 40 with my Khajiit now, and I've basically got him where I wanted - Archery tree finished, Sneak tree finished, and One-Handed finished (as much as I wanted them to be). I was trying to think about what else I could add to him, that wouldn't be super overpowered, but would also work well with a bow a dagger. Any ideas?

Conjuration maybe?

Light Armour?

Sneak?

Pickpocket?

Erm... I dunno what else.

Lockpicking, Alchemy to make poisons, smithing to make your own dwarven arrows (or lower smithing just to make steel ones). Speech because Khajiit are natural merchants, traders and liars (spys). Can't think of anything else but maybe Restoration skill to heal.
