This new addition of Shadow Mission is pretty difficult, is comparable to that of Defeat Shadow Wizard.
1~8 Players
1 Hour limit.
Mission begin in Starting Hall, there will be 8 monster spawned and a counter on the side. The counter is the amount of the monster you need to defeat, not counting the first 8, which is 45. So for this part, you need to defeat 53 monsters.
This rooms in the mission can be divide into 3 type of rooms.
Number rooms: it is like the first part with a pole in the room, hitting it will spawn 8 monster, but this time the counter is 60 not counting the first, so you need to kill 68 monsters for this part.
Pole rooms: 4 waves of enemies will appear, you must defeat all enemies before next wave to appear.
Circle pole rooms: A circle of 24 poles with a pole in the center. Hit the center pole to start, it will spawn 4 Fallen Alchemists, then red/black sulfur spiders (does not explode when killed) will spawn randomly from 1 of the gates. The spawn method have 2 type, 20 spiders at once, or 1 by 1 and at the end 20 sulfur spider will spawn at once. To clear this type of room, you either hit all 24 poles (make it dark), or you kill all enemy.
Boss is Giant Sulfur Spider with black/red spider, defeat it and mission is cleared (Giant Sulfur Spider will explode when killed < <).
This mission have some rare clothing reward like Romantic Feather Cap etc.
