I have open a discussion regarding the paradox of character building for power leveling, but now it comes to me that there are indeed Fortify Attributes Spells. So now, why need to power leveling if we can boost attributes through magic?
Strength damage cap is at 100, Agility damage cap for bow also 100.
To power level in each level up need a lot of work, set up major and minor skills, keep tracking on how much the skill rise.
But to boost attribute using magic is much simpler, just learn that magic and have sufficient magicka to cast it.
A melee character don't need more than 100 Strength to get Strength damage bonus, and so bow user also don't need Agility more than 100 for bonus damage
If correctly set up and spell creating we can make 100 attribute in all attributes using spells
This makes me think to revise my character.
