Nebula Arcanum

The Nebula Arcanum is a magic weapon that produces a pink and black swirling orb. The orb will home in on enemies, either using all its power to deal the most damage it can or dealing enough to kill the enemy, then seek a new target. The orb will deal only 80 damage (unless increased by armor, accessories, or modifiers), but the damage can be spread across multiple different targets so long as the initial target does not take 80 damage points or more to kill. Once all the damage the orb can deal has been dealt, it will explode with no harm to surrounding blocks. The projectile will dissipate after approximately 10-20 seconds.
