Ashen,

Actually i should have explained the size thing a bit better.

The idea behind the spell is to change the hieght of the character,but whlist keeping all his attributes.

Say you are the size of a dwarf and you are fighting an orc.

Now when you are hitting the orc you would be only be able to hit at his knees.
So only that specific armour would be protecting him.
In the same way the orc would be hitting your head(becasue he is taller and cant reach down) and so only your helmet has any armour use.

So the idea is if you head gear is pretty good and you see your opponent having weak boots or leggings than it is an advantage to use this spell.

Basically the spell changes your height but nothing else.

Yes i would have liked to see giants/ogres in the game as well,wielding big clubs and yes probably the sizes between the orc/human/elf are small but maybe that could be adressed?

To add on to the idea,i keep wondering how i can enter dwarves houses since my character is so tall. Doesnt fit with my logic.

So investing in this skill for me is an advantage becuase it may help with fighting and it would enable you to enter into smaller dwellings of different races.
(Perhaps to find something interesting.)
