I dont know if its a bug or feature but seems that necromancer slaves are somewhat broken in 3.0.6....

My PC is 50 lvl necromancer with enhanced fate smiles and lucky intrinisics.

But when I've created lich from uncursed warewolf king corpse on d50 his level (lich) was only lvl8... soon he adjusted to power but just only to 23 lvl- but still to weak to fight monsters at d50
I was really dissapointed because he was simply not ready...

Same situation was on SMC I wanted to create Lich from blessed titan corpse so I boosted my wilpower and mana to the max and putted on crown of science for extra danger level before entering SMC...
result - 18 lvl lich with thousand of hp but with pathetic damage output WTF...

Seems that it affect most of slaves becouse I have some corpse fiends and spectres that never adjusted in power so they mostly usless... they just cannot improve.

Am I doing something wrong ?

Adjusting in power only works randomly or only when PC is leveling up ?

Can somone explain me mechanism or should I report it as a bug ?
