Star Cell

The Star Cell is a Hardmode, post-Lunatic Cultist enemy spawned by the Stardust Pillar during the Lunar Events. It floats slowly towards the player, but can move at a faster rate if the player begins moving away from it.

Upon death, it splits into smaller versions of itself. If these small Star Cells are not dealt with, they will grow into a full-sized Star Cell, that can also split into smaller Star Cells. Small Star Cells do not contribute to the kill count required to break the Stardust Pillar's shield, though after growing back, they do.

Tips

 * It may be to the player's advantage to leave the smaller Star Cells alive. This allows them to gain banners and demolish the Stardust Pillar's shield faster.
 * Use weapons with a large area of effect, as they tend to appear in clusters and you can hit them all at once.
 * The Solar Eruption can kill a Star Cell and all the smaller cells it spawns in a single strike.
 * The Vampire Knives are a very effective weapon against Star Cells, hitting multiple copies of the enemy while healing the player for each hit.
 * The Flairon can also be very effective. Due to the fact that it can summon lots of homing bubbles in a short amount of time, it can easily take out the small Star Cells that the Star Cell splits into.
 * The Inferno Fork, Nebula Arcanum, and Celebration perform outstandingly well against these enemies. The beam spread attack from the Last Prism also works.
 * The Aerial Bane can be good for taking out the Star Cells as it will kill the cells and then the arrow clusters from the bow will kill the small Star Cells.
 * The Life Drain deals a reasonable amount of damage to them at a high rate, can target any number of them at once, and additionally can increase the player's health regeneration.
 * As the Stardust Pillar itself spawns Star Cells, staying away from it will greatly reduce their spawn rate.
 * Intentionally leaving smaller cells alive and using a room to keep them out, a weapon that fires through walls can easily destroy them, and thus breaking the shield with even more ease.

Trivia

 * The tooltip of the Stardust Cell Staff saying: , hints that Star Cells may be disease-causing somehow.
 * In real life, living cells divide into two identical copies of themselves via . Each of these copies can then grow and divide again, similar to the Star Cells. However, real cells split normally and are killed completely, while star cells only split when the player attacks them.
