The 6 favored skills for the Thieves Guild are:
Marksman
Short Blade
Light Armour
Acrobatics
Sneak
Security
To advance to the next levels:
Rank..........AGI.....Per.....1 Fav Skill......2 Other Fav Skill...
Operative......30......30..........40............. ....10...........
Bandit.........31......31..........50............. ....15...........
Captain........32......32..........60............. ....20...........
Ringleader.....33......33..........70............. ....25...........
Mastermind.....34......34..........80............. ....30...........
Master Thief...35......35..........90.................35. ..........
Having your agility and personality at these levels and the above favored skills from the list above at the levels beside the rank, plus doing your "duties" will allow you to adavnce in the Thieves Guild. Hope this makes sense.
