Reck, thats nonsense....
Damage bonus % is the bonus added to the skill %
example, light chop 4, is 900 dmg + 100% bonus (100% of your base atk)
with 10% damage bonus that becomes 900dmg + 110% bonus
so if i had 2k base attack, the first one gives me 2900 damage with light chop 4
the 2nd way with the damage bonus, gives 3100 damage with it
