Ultima Underworld II

Aim of the Game

You control the Avatar of Britannia who, along with many of the realm's heroes, has been trapped inside Castle British by a giant sphere of blackrock, put in place by the evil Guardian. The main objective is to find a way to escape the castle by breaking the blackrock sphere. In the process the Avatar needs to visit eight alternate dimensions to discover clues on how to break the Guardian's spell:

• World 1: Prison Tower
• World 2: Killorn Keep
• World 3: Ice Caverns
• World 4: Talorus
• World 5: Scintillius Academy
• World 6: Pits of Carnage
• World 7: Tomb of Praecor Loth
• World 8: Ethereal Void

Objectives

There are three main quest streams that need to be completed before the endgame can be triggered:

• Find eight small blackrock gems (one from each alternate dimension), have the gems "treated" by Nystul (the castle's resident mage) and merge each small gem with the giant blackrock gem in the lower level of the castle sewers
• Cut the Guardian's "lines of power" to the eight alternate dimensions by first assembling Altara's Rod and using it in each dimension in a place where the Guardian draws power
• Trap an air daemon in the Avatar's body:

 - Mix Basilisk Oil (clear potion) with Filanium mud (the mud is located in the Ice Caverns world, near the Yetis)
 - Bathe in the mud
 - Immerse the Avatar in lava to solidify the mud
 - Drink a potion of Iron Flesh (actually casting the spell will do, but it needs quite a high level)
 - Take a Djinn Bottle to the "Sigil of Binding" in the Ethereal Void and break the bottle in the centre
