To help celebrate the Nightstalker's launch, the publisher is giving away an item code that can unlock free in-game rewards "including 10 Resurrection Scrolls, 5 Extreme Training Potions (100%) (one hour), Town Travel Level 1 (three days) and School look gear set (seven days)." Special prizes are also reserved for anyone who can get their Nightstalker to level 50. Both of these promotions run from now until March 26.
