Spear Mastery

From Diablo 2 Wiki

Spear Mastery

Required Level: 6

Prerequisites: None
Notes: Bonuses only apply when a Barbarian has a spear equipped. Javelins are a type of spear, and this skill will boost their damage when used for melee, but not when thrown. Throwing Mastery comes into effect then.

Spears are very big damage weapons, and once Lances were finally enabled in D2, they became by far the most popular weapons for WW Barbarians, due to their huge damage and range. They aren't as useful in D2X due to the Attack Speed being so slow, but with some decent IAS on the Spear and more on gloves and other items, and the massive damage of a Cruel War Pike, this is the most effective WW weapon.

It's less useful for other combat though. Berserk is a slow hit with a spear, even with IAS equipment, and spears have relatively high Dex requirements.
