Weapon master

For a weapon master, perfection is found in the mastery of a single melee weapon. A weapon master seeks to unite this weapon of choice with the body to make them one and to use the weapon as naturally and without thought as any other limb.

The weapon master was introduced by the 3rd Edition sourcebook Sword and Fist. Though not necessarily canon to the Forgotten Realms, the weapon master was available as a prestige class to players of Neverwinter Nights and Neverwinter Nights 2.

Source of Power
Like other classes such as the monk, red avenger, and master samurai, the weapon master uses an esoteric force known as ki to increase his lethality in combat. His goal is to unite his weapon of choice with his body, and be able to use it without conscious effort as naturally as he would use any other limb. Individual weapon masters are often named for their weapons: for instance, a weapon master who uses longswords would be a "longsword master," a warhammer wielder would be a "warhammer master," etc.

Weapon Master Abilities

 * Weapon of Choice : At first level, a weapon master selects one melee weapon type (e.g. longswords, kukris, etc.) to use exclusively as their Weapon of Choice. Their weapon master abilities only function while wielding a masterwork weapon of that type.  Monks can select their unarmed combat style.
 * Ki Damage : Once per day per level, a weapon master may choose to make a special attack with his weapon of choice. If this attack hits, it automatically inflicts maximum damage.
 * Increased Multiplier : At second level, a weapon master can focus ki to improve their chance of landing a critical blow once per day. They gain an additional use of this skill at each even-numbered level thereafter.
 * Superior Weapon Focus: At third level, a weapon master's blows become more accurate.
 * Superior Combat Reflexes: At fifth level, a weapon master gains impressive skill at striking retreating targets.
 * Ki Critical : At seventh level, a weapon waster's critical threat range increases by 2 when using their Weapon of Choice.
 * Ki Whirlwind : The weapon master's whirlwind attack becomes much faster, doing the same amount of damage in less time.
