Star Cells are an enemy that spawn after defeating the Lunatic Cultist, near the Stardust Pillar. Small Star Cells are a smaller version of Star Cells spawned when they are destroyed. Upon death, the larger version splits into several smaller Cells. If these are not killed fast enough, they grow back into regular Star Cells, and will continue attacking the player, effectively multiplying.
- Rarely when a star cell splits the small star cells sprites are bigger than they should be.
- The Small Star Cell Banner does exist, but there is no valid kill count for Star Cells, therefore the banner will not drop.
- The maximum amount of Star Cells and Small Star Cells on screen at once is ten.
- Added to the game.
