This new world will have some geographical changes such as the removal of enclosed oceans and all continents having individual IDs to make adding quests to the game easier. In addition, there’s been adjustments made to unarmed and melee combat that puts fighters at factor 2 on even footing, while earning skill in these disciplines longer to do. The world reset will also make several adjustments to LP and gains. The world reset is scheduled to occur on March 6th.
