A rapier is a military one-handed melee weapon in the light blade weapon group.[PH:218][HotFL:331][HotFK:334][MME:21]

Ardents, avengers, barbarians, battleminds, fighters, paladins, rangers, wardens, and warlords are proficient with all military melee weapons, including the rapier. Assassins and swordmages are proficient with military light blades, including the rapier.

Other classes and races do not have proficiency with the rapier as a class or racial trait, but any character can become proficient by taking a Weapon Proficiency feat.

The rapier was originally a superior weapon in the Player's Handbook. The Essentials rulebooks changed it to a military weapon.
