The spear is the basic, definitive weapon within its category. A little stronger and heavier than the javelin, this two-handed weapon's effectiveness in combat and it's chance to hit when thrown are modified by the Spear skill.
While the northern spear, the Kaumolais spear and the ango all have slightly higher Point ratings, none of these seem to be available in anything other than standard quality. Therefore, a masterwork spear is likely to be the 'best' spear in terms of damage potential.
The spear has a long wooden shaft and blade specially designed for melee combat.
