wow gold: The most powerful spear you can buy in shops but no slots
Harbert: Not a quite good spear but you can put slide wider card because it is very hard to get two slotted one unlike a Parzilan. Harbert had 165 atk power and does 800+ wow gold atk power if you put slide wider card.
I also use this spear when I use spear paladin and put slide wider card inside and it do lot damage. This is the spear you use as it can reduce the tridents you carry, but take note that your STR must be higher than 65 in order to use it.
Lance: A spear that have 185 atk powers. The most powerful spear you can buy in shops but no slots, I recommend you not to use this spear but a +5 hybld harbor or a +5 hybld hurricane Herbert will do the job. If you want it, get an element one.
Rare spears: Rare two hand spears are hard to find but I got some info on some of them.
Zephyrus: I haven seen it before but it is a strong spear best for killing water element monsters because it is wind element. You can get it from stormy knight.
Longinus's spear: A dark element spear that does 180 atk powers, I don't know kill what monster can get it but it is quite strong.
