Hi, I'm new to the server and im looking to find out which proffessions are able to duel wield and what kind of abilities that they present....... also which one is better for pvp... I am a Elf btw
No elf gets masteries for duals. The best PvP classes for Elves are Silver Rangers (archers) and Spell Singers (mages). Both are over powered for PvP due to stacking buffs, but neither use duals. :p
well ..... if you consider dark elfs as elfs too .. then go defintly for bladedancer with duals - with their dances they are very welcome in any group and alone are a wonderful look when fighting. Just accept that they are a bit .. darker ^^
my advice, start here (http://www.lineage2.com/Knowledge/race_elf_changejob.html)
read the class desriptions for the second class changes (for elf fighters they are temple knight and swordsinger).
then, when you find a desription you like, go to the skills page here (http://www.lineage2.com/Knowledge/race_elf_skill.html?my_class=elf_swordsinger)
note that as a swordsinger you can use duals. you just look sort of silly. some people like silly tho.
last step: when you have it narrowed down to a couple classes, ask people who are high-level in those classes if the class is right for you. personally, i like using low-hp skills, so destroyer is fun for me. you said you liked dual swords, blade dancer (dark elf) and gladiator (human) are the only classes that get masteries in them.
