This is a korean Cooperative Defense/SkillWar map.

There are several levels throughout the game - you must kill monsters and stuff to gain $.
After each level there is a Boss. The objective is to keep the Castle Master (Aldaris in the middle) alive.

Systems:

Items -
Nothing special, you can buy items in the shop (by MCing in upperright when you're next to the shop)
Healing Potion (40$) - Heals you to max and adds +100 mana by using Corsair.
Skill 2 (500$) - obviously Enables Carrier Skill.
Skill 3 (1100$) - obviously Enables Arbiter Skill.
Mana Amulet (1200$) - Increases maximum Mana.
Mana Ring (1500$) - Increases Mana gain speed.
??? (2000$) - ???

Skills -
You have 3 skills (Scout Carrier Arbiter). You also have various hidden combos, however, those are unknown.
Even though you have 3 skills, the best part is that you can extend the skills by using another one. Time it right!

Revive -
You can revive your fallen teammates by going to the Hero Altar, and MCing their color in the upper mid (800$).


It's hard, challenging, yet fun.
