This rapier-like weapon is the size of a short sword, but weighs only as much as a dagger. Dexterous elf fighters and rogues favor it. Its thin, flexible blade slips easily into the seams of armor or between the ribs of a foe. Some elf nobles carry a lightblade—often decorated with intricate filigree and tiny gemstones—as a sign of their station, even if they aren’t proficient in its use.
You can use the Weapon Finesse feat with this weapon.
Characters proficient with the elven lightblade may treat it as a rapier or a short sword for the purpose of any of the following feats: Greater Weapon Focus, Greater Weapon Specialization, Improved Critical, Weapon Focus, and Weapon Specialization.
Creatures with the Elf subtype may treat this weapon as a martial weapon.
