Question about Armor and Weapons and styles : Lineage 2 General Discussions

I am playing a level 17 Elven Fighter at the moment. I have a 33 PK with Brig armor and dual swords. As an elf archer, do I get a penalty for wearing Heavy armor? Do I also get a bonus to Chance to hit or Damage for training in Power Shot with my bow? or is this just for the power shot. I seem to hit more often after I trained in my dagger styles then when I didnt.
Your thoughts are appreciated.

no the pwoer shot skill just for doing dmg with Power shot. it doesnt affect ur dmg/accuracy with ur bow.

Is this the same for Sword and Dagger Styles?
Training in them does NOT effect your damage/accuracy?

when you say dagger/ sword styles you mean:

power strike
mortal blow

right? if so then no, training them does nothing to improve your dmg/accuracy
