This greatsword has a wavy blade and an oversized hilt adorned with six spikes.

Manticore greatswords were designed to mimic the spike-throwing ability of their namesake creature. Such a weapon functions as a +1 greatsword. When you activate this weapon, you can launch either one spike (a standard action) or all six spikes (a full-round action) from its hilt as a ranged attack that provokes attacks of opportunity. Treat the spikes as thrown weapons.
Each spike deals 1d6 points of piercing damage and has a range increment of 20 feet. The spikes have an enhancement bonus equal to that of the weapon, and are treated as being made of the same material and having the same alignment (if any) as the weapon. The spikes crumble to dust 1 round after they are launched from the weapon. A manticore greatsword regenerates any thrown spikes at dawn each day.
