Lich (Purple Globe 4)

This Lich can be encountered in Baldur's Gate II: Enhanced Edition and Baldur's Gate II: Throne of Bhaal games on the Watcher's Keep Final Seal dungeon, when operating the Globe Machine.
==Gameplay==
After the party presses the purple button on the Globe Machine and receives the fourth Purple Globe - this lich spawns (along with a Elemental Lich).
This undead mage will appear and initially deploy protection buffs, and if damaged in some manner will further protect himself with a contingency.
Afterwards, if able, he will cast spells as noted under the conditions listed in the InfoBox.
This lich can See the invisible. 
For some reason, this lich only has an 11th level mage experience level yet uses an 18th level spell caster script.
The lich will be particularly susceptible to Turn Undead.
The lich's Remove Magic scripted use is quite low powered by the time Watcher's Keep is typically explored by a party.
When he is defeated, the lich's corpse remains on the ground, but no loot is discovered.

==Mod content==
The Sword Coast Stratagems mod makes some revisions to this creature.
SCS doesn't use this creature (LICH01.cre) in the game at all - instead, it substitutes a random selection of a "generic" lich (nine varieties) to replace this creature, for greater diversity in gameplay.
The lich's experience level is always changed from 11 to at least 25, and will randomly assign a specialty kit at installation, either Conjurer, Enchanter, Invoker or Necromancer.
The assigned kit will determine which AI script is used by the lich, and influence available spell choices, prepared Minor Sequencer, Spell Sequencer and Spell Trigger.
Expect a much more challenging spell casting opponent, with the ability to recognize party buffs/protections, and the means to try and remove them.
On higher difficulty settings the lich will employ various mage High-level class abilities.
