thnx cainehill
my concern against nonundead pretenders was the following :
if i would cast burden of time my nonundead pretender will sooner or later die right ?
if i summon a harvester of sorrow in the province my pretender is in he could get diseased or ?
this 2 spells are quite unimportant though and i can not remember another one like these 2 so if they are the only 2 you are right
a frostfather ... is the far better magic allstar than a GK
perhaps even the main reason which spoke for me against this is a roleplaying one :
a human semigod didn't fit for me as the leader of an undead nation
human necromancers and so on are ok as lackeys but not as the highest leader which becomes the mightiest god
this has to be an undead
