Quote from Kotoshiki;715362:
I came back to Vindictus and I have a few questions. What armor is best suited for a Lann at level 34 and what weapon? I use Twin Swords so please recommend me which is best. Also, should I focus on Armorsmithing or Weaponsmithing?
Weapon and armor really don't matter until you're past Lv. 61. I'd just run whatever armor you have until you reach Spider Lord. Then upgrade that set to Laghodessa. After that you can go to Sinister Plate Mail, or skip it and head off to any of the Lv. 61 sets.
Weapon wise, use the Blade of Ykesha, and upgrade it to Blade of Ykesha: The Nihility. After that, wait until the Ivory Twin Swords and then go to either Dreamwalker Twin Swords or Raider's Twin Swords.
Expertise aren't very useful in the end, though I'd focus on Platesmithing (as Lv. 56 3 Star sets have some use, while Ivories are just outclassed).
