A restricted training guild offering an expensive guaranteed skill increase, with a free first session but staggering upper-level prices.
The guild inside The Desperado Club denies Carl entry but admits Princess Donut with The Sledge. Its training room resembles the party's own but guarantees a full skill-level increase. The first session is free; raising the trained ability to level nine costs twenty thousand gold and level ten costs two hundred fifty thousand.
A magically separated back-room training area accessible through a portal-like doorway from the club vestibule.
The guild advances Donut's spell training while demonstrating the dungeon's steep monetization of high-level skills.
