To take advantage of this, bring a full water team. Weakpoint Effectiveness Every mob with a weakpoint has millions of HP. Hits to weakpoints deal extremely increased damage. To clear certain mobs and the boss, you need to hit the weakpoints. Null Block The main gimmicks of this dungeon are blocks. You cannot move around properly or even deal damage to the boss if you don't have null block. All of your units need null block.
