Character Changes
Players can now obtain a Dual Class when they reach Lv. 105.
After reaching Lv. 105, talk to Dual Class Masters Joachim in the Town of Aden or Raina in Talking Island Village to add a Dual Class.
Lv. 105 or lower characters no longer drop a level when they die, but will still lose XP.
