Just in case you guys were wondering what I've been up to...
More heavy metal in book 2! Screenshot!
You my friend, are a genius
But seriously there is a lot of power to be had for maxing one attribute. I maxed speed in book 1 and killed most enemies in 1 shot.
Strength bonuses to mastery-extra health, damage per 5, and poison resistance.
Speed bonuses to mastery-really high defense and extra damage per 5
Dexterity bonuses to mastery-extra armor and attack, extremely silent, extra pick locks skill, and high chance of critical hits due to high hit rate.
Endurance bonuses to mastery-High health, extremely good bonuses to resistances and relatively makes you a walking tank if you specialize mostly in one weapon.
Concentration bonuses to mastery-High to hit rate, although no extra defense like dexterity, disarm traps bonuses, extra encumbrance and high critical hit chance as high to hit rate like dex.
Your max damage still beat my lvl 14 speed rogue's damage by 4. Nice!
I would say my next build will be a strength build like yours. However, I am going to maximize the backup skills at creation of my character. By doing this, you can give strength 3 points per level with 2-3 points in said weapon every level as well. Im thinking that will fix my low to hit chance i had on my speed build in book 1. I really just don't like relying on dodge.
