Having reached level 30 and mastered the way of the Rogue,
I feel the urge to learn more.
Does Dark Lord of Kerning City have even greater lessons to
teach me?
Dark Lord said that if I can pass his test, he'll gladly teach
me more. I'm no longer the weakling I once was, but hearing
that I still have to face a trial makes me a bit nervous.

Shumi's L35
Construction Site heist chain - just at a different
basement level. Mob density L25-30, in-range for L30 Thieves.
Class naming note: the CoT 2 datamine
labels this class "Rogue" internally to match modern KMS
conventions. Every in-game player-facing text still says
"Thief". Same class - two names.
