         continue

   if item then seen.add(item.hash)
   return item

Magic items

The seed for the Mages Guilds is calculated as (currentCity.id & 0xFF) + (currentCity.latitude) + 1000.

srand(seed)

quality <- getShopQuality()
personality, personality2 <- getVendorPersonality()

if quality >= 3 
   seen <- []
   for try <- (0, 200)
      item <- generateMagicItem(quality)
      if item.hash in seen then continue
   mg.shop.add(item)
   seen.add(item.hash)
endif

Spells and potions

Potions are simply chosen from the list: the names are in szlist @41CF9, prices @41E4C, and the spells added to a new potion item are @41E3D.

Spells are sold at double price. The maximal price for a spell available for sell is 250 * quality.

Buying

Selling

For weapons and armor, the base selling price is (item.price * item.curHealth) / item.maxHealth.

If a magical weapon/armor was sold, it is added to the shop inventory until player leaves the shop.
