A Rogue is the cunning path. Speed, agility, mystery--explains a Rogue and we play the world like a game.
Long ago, before there was magic or much knowledge for that matter, we were warriors. The warrior is a simple fighter, and maybe slower and humble, can be extremely deadly. Many wars were used by the simple blade. But over time, more knowledge was attained. Some fighters found this knowledge, and became cunning. Instead of being slow and seen, they were unseen and quick, which can be a deadly formula. They looted and killed, becoming more cunning after each kill. The Rogue was born, the agile fighter of darkness. We follow the path of riches for we want them, a Rogue is a promising path to treasure.
The Blood is one of the most powerful and versatile weapon for the Rogue. It can be wielded at Level 95 but becomes most effective after Enchanting it at Bon-Hwa. Once a hunting weapon, now it is used primarily in PK but is also the weapon of choice of many Rogues who hunt down various Bosses alone.

Regen is short for regeneration and is the quantity at which you regen per cycle. With 0 Regen bonus, every 25 seconds you regenerate 2% of your character's Vita and Mana. This means if you were 100/50 stats and were injured, every 25 seconds you would regen 2k vita and 1k mana until fully healed.
Regen bonuses from items increase the percentage you regenerate each time. Everyone 1 point of Regen bonus is a 0.02% increase in the amount you will regenerate. So for instance, if you had a Regen bonus of 10 with the same stats, every 25 seconds you would regen 2.2% or 2200/1100 each time.
Regen bonuses can be very useful when it comes to soloing or PKing 1 on 1. Purple potions also boost your Regen bonus for a short period of time.
