This Orb enables the player to kill tough single-tiled monsters in melee combat that are otherwise unkillable with ordinary weapons, such as the Raiders in Ruined City, Skeletons in the Palace, reptiles in Reptiles, salamanders in Volcanic Wasteland, etc.. It allows the player to attack Flail Guards and Hedgehog Warriors directly without the special moves to trick them. It does not work against multi-tiled tough monsters, however.
Butterflies can be killed directly by the player when this Orb is active, but Spinel will not be generated. Spinel is generated only when the Butterfly is killed by a Raging Bull.
