Boreas Seabed (mission)

This mission is basically about getting a spear. Once you enter the mission you will be in a sort of arena. You just have to wait and groups will come to you, they will consist out of some fighters and a boss. You defeat them and you'll get a movie. After this you are allowed to use the spear.

Explanation of spear: The spear will get more and more power if a nearby foe dies, so I suggest you hold it in your hands it get next to enemies. DO NOT DROP THE SPEAR, this will result in some damage, but you need that for the boss at the end. You can use the spear once and find out about this power but the problem is the spear will be level 1 again (max. level of spear is 5). Once you get to a bigger area with a sort of frozen water you'll find groups of beast. Defeat these and the boss will spawn. This is where the tricky part is, the boss will deal high damage with a special monster skill. You can't evade this (as far as i know). Stand next to the boss and drop the Spear, you now see the boss gets a great set of damage. Now you weakened him a bit, attack him and maybe try to charge the spear again with standing next to some beast and kill them. (these beast will be resurrected by the boss). Or you could attack the boss until it's dead.
