New safe-room addition where spells can be trained up, usable by only one crawler at a time.
The Magic Workshop is one of the two new rooms the party bought, leaving them with only 100K gold. It lets spells be trained up much like the regular training room does for combat skills, but unlike the training room only one person can use it at a time. It is also required for some of Mordecai's higher-level potions, though Carl isn't yet clear how that part works.
Mordecai has already mapped out a strict schedule for it: Princess Donut pushing her Magic Missile, which has stalled at level 11 despite constant use, and Carl grinding his Fear spell, stuck past level five. Carl quietly overrides that, messaging Donut to work Laundry Day instead.

The party's spell-leveling facility and a bottleneck they must share by schedule.
