Aeosian spear

A type of vibro-blade spear was used by Aeosians on the planet of Aeos Prime. When these spears were activated, the connecting point between the spearhead and the staff glowed, and electricity began to arc around the blade. When activated, the spears were capable of disabling an aged B2-series super battle droid, and blocking blaster bolts. The spears had a second point above that main blade, the tip of which glowed blue when the spear was activated. These spears had a gold material fashioned onto them, mostly around the point between the staff and the spearhead.

A variant of this spear was used by the the tribe's queen, which had more gold material fashioned onto it, and two points from the side edges of the main blade, giving it the appearance more akin to a trident.
