Yesterday, I reached level 15 and got the ability to equip a backup weapon. My question is regarding weapon skill-ups. How are they calculated? I have been using strictly a one-handed weapon and shield. Now I would like to work on leveling up a second type of weapon, such as dual-wielding. I have read that you get skill-ups based on what skills are in your ability bar. So can I fight a mob and get it to a sliver of health with my main weapon and then switch to my backup for the kill to get the skill points to go into my backup?
