There are four levels that a student can have when selling you items.
Domina will always be level 1. You might miss shop levels 2 and 4 if you are'nt
careful. Make sure to save Geo for a far away space on the map so that it will have
level 4 shops. Geo has the best level 4 shop equipment in the game. The same applies
to the instruments shop in Geo. A good way to get shop level 2, is to place a town
as far from home as possible just as you are about to begin the first of the three
major quests at the start of the game.
1. Cheap Manastones, etc.
2. Steel, Silver, Obsidian, etc.
3. Gold, Ebony, Hemp, etc.
4. Platinum, Maple, Iron, etc.
*If all four student shop levels are obtained and Duma Desert's Dryad level is 3, an extra quest
will be awarded as a bonus.
