When Pools of Darkness and FRUA both occur in the Forgotten Realms their item lists are likely to be similar.
As FRUA and Dark Queen of Krynn are found on separate worlds there will be some differences. Even so, of items 1 through 254, 235 are found in all three of DQK, PD and FRUA.
Differences are caused by
(1) Unique Krynn item:
(2) Krynn having separate White and Red Robe Wizards:
Red Mage Scroll 3 Spells, Red Mage Scroll 3 Spells, White Mage Scroll 3 Spells, White Mage Scroll 3 Spells
(3) Krynn has no Drow, subterranean Elves. Forgotten Realms has no Kender, Tinker Gnomes or Solamnic Knights.
Item #222, all three are cursed, so differences in item type is not important.
DQK item 202: Gauntlets Of Ogre Power, is the same as FRUA item 233.
