Disc of Repulsion

The Disc of Repulsion is an artifact from Hexen. When activated, it hurls nearby enemies and projectiles a safe distance away from the player, dealing a small amount of damage to any monsters that collide with a wall or other object, including another enemy. Monsters that collide with one another will start fighting as if they had been attacked.

Like other artifacts the Discs are stackable, and up to 25 may be carried at a time.

Strategies

 * The Disc of Repulsion can be used to deflect incoming projectiles. Due to the upward angle of repulsed objects, the deflected projectile generally won't strike the creature that fired it.
 * Non-boss enemies can also be thrown back by the Disc. This can help keep melee attackers at a safe distance.  Enemies thrown by the Disc will take damage if they strike a wall or other object.  If they hit each other this way, they may begin to infight.
 * Walking creatures harassing the player near a cliff can be flung over the edge to their deaths.
