️New Updated Introduction–Eternal Battlefield
Players will be divided in two teams in this new dungeon. At the first stage of the dungeon, players will need to defeat their enemies and protect their base. In the second stage, it will be time to attack the enemy base. Win to receive Class EXP and Class Equipment.
There are other changes, but these are the new additions. They are for ult. 7, though, so most players here probably won’t encounter them for a short while. Well, unless they’re Dante.
