Ultima II: The Revenge of the Enchantress/Pangea age


 * In 1423 BC, in Castle British, the subdued balron whimpers: Lithium packs the 16th level!

Tri-lithium is necessary for space travel.

In the original version of Ultima 2, dungeons and towers are completely optional, because tri-lithium can also be dropped by defeated thieves. In the Japan-only FM-Towns port, enemies do not drop tri-lithium anymore, therefore there is a reason for exploring dungeons and towers.
