Can't Finish Dungeon - ReaperX

(Lv. 185) - Northern Lands

For Nightmare, you’ll need a really strong build with high damage. Of course, our Auto Dodge isn’t 100% perfect yet, so you might still die 2-5 times.

The faster you can kill the enemies, the better

For Mage Class, I recommend these skills:

Lightning Burst (Lv. 175)
Geyser (Lv. 185)
