Blackhole Cannon use animation. Note the singularity drawing in the Wraiths and Undead Vikings to damage them.

The Blackhole Cannon is a craftable Hardmode magic gun that fires a projectile which creates a singularity on impact with an enemy, block, or cursor position. The singularity sucks enemies towards its center while dealing constant damage, and lasts for 5 seconds. Only one singularity can exist at a time; any new ones created will override the previous one.

Its best modifier is Mythical.
