I've added some restrictions in skills.
Now if you have specialised skill or spell, and
have specialised skill or spell of oppose class,
then skill practiced percent will be reduced.
Here is table of opposes:
Abjuration has necromancery and transmutation in oppose.
Conjuration has divination and invokation in oppose.
Divination has conjuration and some enchantment in oppose.
Enchantment - invokation, some divination.
Invokation - conjuration, enchantment.
Illusion - necromancery, some abjuration.
Necromancery - invokation, illusion, transmutation.
Transmutation - abjuration, some illusion.
Berserker - stalker, shwashbuckler, ranger.
Ranger - berserker.
Now you are to deside what can you practice and what not.
If you practice all, then all your specialised skills
will be in down.
If there is any problems, or suggestions, then write me
a note on personal board. 
Next i will try to handle lua problem with orcs area.
Worst regards.   Ger.
