What is the best strategy to defeat the Stardust Pillar's cells in Terraria?

Defeating the Stardust Pillar's cells in Terraria requires a solid understanding of the mechanics involved, as well as careful preparation and execution. The Stardust Pillar is one of the four Celestial Pillars that appear during the Lunar Events, and it is associated with the Summoner class. The pillar itself is surrounded by a shield that can only be broken by defeating a certain number of its associated enemies, which in this case are the Stardust Cells. These cells are unique in that they split into smaller cells when damaged, making them particularly challenging to deal with.

To begin with, it is important to understand the mechanics of the Stardust Cells. When you attack a Stardust Cell, it will split into smaller cells, and these smaller cells can also split further if they take enough damage. This means that if you are not careful, you can quickly become overwhelmed by a large number of small cells. The key to dealing with this is to use weapons that can either kill the cells quickly before they have a chance to split, or to use weapons that can hit multiple cells at once, effectively managing the swarm.

One effective strategy is to use weapons with high single-target damage to quickly eliminate the larger cells before they can split. For example, the Solar Eruption, a powerful melee weapon, can deal significant damage to a single target and has a wide area of effect, making it useful for hitting multiple cells at once. Similarly, the Daybreak, another melee weapon, can be thrown and sticks to enemies, dealing damage over time. This can be particularly effective against the larger cells, as the damage over time can help to finish them off even if they split.

For ranged characters, the Phantasm, a bow that fires multiple arrows, can be very effective. The arrows can hit multiple cells, and the high rate of fire can help to quickly reduce the number of cells on the screen. The Vortex Beater, a gun that fires explosive bullets, is another good option, as the explosions can damage multiple cells at once.

Magic users can take advantage of weapons like the Razorblade Typhoon, a homing projectile that can hit multiple targets, or the Lunar Flare, which creates a beam of light that damages enemies in a straight line. Both of these weapons can help to manage the swarm of cells effectively.

Summoners, who are particularly suited to this pillar, can use minions like the Stardust Dragon or the Stardust Cell staff. The Stardust Dragon is a long, serpentine minion that can attack multiple enemies in a line, making it ideal for dealing with the cells. The Stardust Cell staff summons a cell that attacks enemies and can also split into smaller cells, mirroring the behavior of the Stardust Cells themselves. This can be very effective, as your minions can help to manage the swarm while you focus on dealing damage.

In terms of preparation, it is important to have a good set of armor and accessories. For melee characters, the Solar Flare armor provides excellent defense and boosts melee damage. Ranged characters should use the Vortex armor, which increases ranged damage and critical strike chance. Magic users will benefit from the Nebula armor, which boosts magic damage and provides a chance to spawn buff orbs when enemies are killed. Summoners should use the Stardust armor, which increases minion damage and allows you to summon an additional minion.

Accessories should be chosen to complement your class and playstyle. For example, the Celestial Shell provides a variety of buffs, including increased damage and defense, and is useful for all classes. The Ankh Shield provides immunity to a variety of debuffs, which can be very helpful in the chaotic environment of the Lunar Events. The Worm Scarf or Brain of Confusion can provide additional damage reduction, which is always useful.

Potions are also an important part of preparation. Ironskin potions increase defense, while Regeneration potions provide health regeneration. Endurance potions reduce damage taken, and Lifeforce potions increase maximum health. Swiftness potions can help you move quickly to avoid attacks, and any class-specific potions, such as Archery potions for ranged characters or Magic Power potions for magic users, should also be used.

When engaging the Stardust Pillar, it is important to have a good arena set up. A flat area with platforms can help you move around and avoid attacks. Heart Lanterns and Campfires can provide health regeneration, and Bast Statues can increase defense. It is also a good idea to have a Nurse nearby, as she can quickly heal you if you take too much damage.

One common mistake is to focus too much on the larger cells and ignore the smaller ones. While the larger cells are more dangerous, the smaller ones can quickly overwhelm you if not dealt with. It is important to balance your attacks between the larger and smaller cells, using area-of-effect weapons to manage the swarm.

Another mistake is to underestimate the importance of mobility. The Stardust Cells can move quickly and can easily surround you if you are not careful. Using accessories like the Master Ninja Gear or the Shield of Cthulhu can help you dodge attacks and move quickly around the arena.

Advanced techniques include using the Rod of Discord to teleport out of dangerous situations, or using the UFO mount to stay airborne and avoid ground-based attacks. The UFO mount is particularly useful, as it allows you to focus on attacking without having to worry about movement.

In summary, defeating the Stardust Pillar's cells requires a combination of high-damage weapons, good armor and accessories, and careful management of the swarm. By using weapons that can quickly eliminate the larger cells or hit multiple cells at once, and by preparing with the right potions and arena setup, you can effectively manage the swarm and break the pillar's shield. Avoiding common mistakes like ignoring the smaller cells or underestimating the importance of mobility, and using advanced techniques like the Rod of Discord or the UFO mount, can further enhance your chances of success. With the right preparation and strategy, you can defeat the Stardust Pillar and move on to the final battle with the Moon Lord.
