Lightsaber bomb

A Lightsaber Bomb is an explosive device disguised as a regular lightsaber hilt. The first was made by Geist Weiss and the explosion was equal to a thermal detonator. However, later versions, such as Aÿisha Remy's lightsaber bomb used to destroy the Jedi temple on Coruscant and Darth Vires' Varek Rayth's lightsaber bomb that almost destroyed the Sage Halls, were equivalent to plasma bombs.
