Damage bonus added to your weapon base attack, but not final.Additional damage not working for 45 rare7 bow.
a change of rank 40 to rank 100 (which is what i test) have no perceptible changes on skill/basic attack damage.
All monsters doesn't have additional defence, in this case if additional damage +2000 (example) to your total damage added 2000 absolute.it would be nice if that system worked for monsters too...
