lichdom
Liches are powerful magic-users who have dedicated their lives to the
power of black magic. They sacrifice their physical bodies in return for
eternal life so that they may forever learn and seek knowledge in their
art.
To invoke lichdom the necromancer mage must first have gained access to the
spell 'lichdom', learned only after mastering certain prerequisite spells
such as negative channel, animate dead and one or two others. (See help
'secrets').
Lichdom is not easy, and even should a necromancer obtain all of his
lich-quest items he or she is not guaranteed a successful transition to
undead state. If a necromancer does wish to still undertake this
transition, he or she must obtain the items from the lichdom spell, and
give them to Chemosh for brewing into a special potion.
