Orb of the Sword II
The Orb of the Sword II is a complementary orb to the Orb of the Sword. While it is active, it generates a sword of pure energy that floats next to the player and moves along with the player, but pointing in the opposite direction to the sword generated by the Orb of the Sword. Like the latter, it is a very powerful weapon, capable of killing many monsters that usually cannot be attacked directly, as well as destroying barrow walls in the Burial Grounds along with a few other wall objects. Monsters recognize its power, and will avoid moving towards the tile the sword occupies.
Just like the Orb of the Sword, the generated sword cannot be directly manipulated by the player; the hyperbolic geometry of the game must be exploited in order to cause the orientation of the sword to change with respect to the surrounding world. If the player manages to retrieve 25 ancient treasures, the sword will be upgraded to become capable of destroying even more objects.
