Whats the difference between PvP chars and Role Playing Chars?

Role Playing characters play through the story of the game, and start at Lv1 with no skills or items. Any skills, item upgrades, and runes you find with a Role Playing character becomes "unlocked" for your account.

PvP characters start off at max level (20), but they cannot go to any non PvP maps. They have equipment with the best stats, but they are limited to item upgrades, skills, and runes that the account has unlocked with a Role Playing character.

Basically, if you try to immediately PvP with a PvP character, you're going to get killed because you don't have any skills, or any runes on your armor, or any item upgrades on your weapons. You have to unlock items with an RP character first.

You can choose for the Pre-made pvp characters, and you will have 8 skills that are set for that model
