WOW Gold: There are many skill points left over max up your magnum to level 10
Weapons (two handed spears)/equipments needed/recommended cards: The spears that you use have many types, when you buy a spear with slots and put a card inside, everything will be change WOW Gold so I will tell you what spears are the best.
Note that spear quicken only works on two hand spears so I will only mention two hand spears here.
Note: there are many skill points left over max up your magnum to level 10 and your one hand so that you can be both one hand and two hands. If you have additional points, left over after max up all of that max shield charge to level 3 and get shield boomerang.
Gursaime: The most lousy two hand spear even with three slots, it is best not to have it.
Partilan: Quite a good spear because of its high atk but most only two slots.
Trident: The trident that king trident use in the movie the little mermaid. The most welcome spear by most knights and has 3 slots the most, the most recommended spear you will have to use.
Bill gisarme: The brother of the spear gisarme does 183 atk that's high but hard to get. If I am right you can get from guild treasure box or old blue box.
