Mastering the Spectral Summons: A Guide to Spawning Polterghast in Terraria Calamity

So, you want to tangle with the Polterghast, eh? This ethereal terror from the Calamity Mod isn’t just lying around waiting for a good fight. You need to know the secrets to coaxing it into the mortal realm. Fortunately, there are two distinct methods to achieve this spectral showdown.

The primary way to summon Polterghast is by using a Necroplasmic Beacon within the confines of the Dungeon. This method is available at any time, provided you have the necessary materials to craft the beacon. Alternatively, if Polterghast has not yet tasted defeat in your world, it will materialize naturally after you’ve vanquished a total of 30 Phantom Spirits. These spectral entities haunt the Dungeon after the Moon Lord has fallen. Now, let’s delve deeper into these methods.

Decoding the Necroplasmic Beacon

The Necroplasmic Beacon is your key to a controlled summoning of Polterghast. But how do you get your hands on one? The crafting recipe requires a trip to the depths, a dabble in necromantic energies, and the right workstation.

Gathering the Ingredients

To craft the Necroplasmic Beacon, you’ll need the following:

• Ruinous Soul (5): Sold by the Arc NPC, who moves in after you defeat Polterghast for the first time. This does present a slight catch-22, as you need to beat him once to guarantee future easy summons.
• Ectoplasm (10): Dropped by dungeon spirits after defeating Plantera.
• Souls of Fright (5): Dropped by Skeletron Prime.
• Souls of Might (5): Dropped by The Destroyer.
• Souls of Sight (5): Dropped by The Twins.

Crafting the Beacon

Once you’ve gathered all the ingredients, head to a Mythril Anvil or Orichalcum Anvil. Combine the materials there, and voila! You have a Necroplasmic Beacon.

Summoning the Specter

With the beacon in your inventory, travel to the Dungeon. Ensure you are within the Dungeon biome. Then, simply use the Necroplasmic Beacon. Polterghast will materialize, ready for battle!

The Phantom Spirit Gambit

This method relies on the natural haunting of your Dungeon after the defeat of the Moon Lord. Phantom Spirits will begin to spawn within the Dungeon biome. This method only works if Polterghast has not been defeated yet. Killing 30 Phantom Spirits will trigger the automatic summoning of Polterghast.

Hunting Phantom Spirits

Equip yourself with gear suitable for post-Moon Lord dungeon exploration. Focus on weapons that can quickly dispatch the Phantom Spirits, as you need to eliminate a fair number of them.

The Inevitable Arrival

Once you’ve slain your thirtieth Phantom Spirit, prepare yourself! Polterghast will materialize soon after. He is no pushover, so be ready for a challenging fight.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions about Polterghast, ranging from its abilities to associated items and content unlocks:

1. Can Polterghast spawn naturally without Phantom Spirits or the Beacon? No, Polterghast requires either the use of a Necroplasmic Beacon or the defeat of 30 Phantom Spirits to spawn in the Dungeon.

2. Why does Polterghast despawn? Polterghast will despawn if you venture too far from the Dungeon, particularly if you reach the surface. Staying on the surface for more than 10 seconds will cause him to accelerate away and disappear.

3. How do I get Polterplasm in Calamity? Polterplasm can be obtained as a rare drop (10% chance) from Dungeon Crates and Stockade Crates after you have defeated Polterghast at least once.

4. What happens after I defeat Polterghast? Defeating Polterghast unlocks several things: The Arc NPC can move in, mini-bosses in the Abyss will start dropping weapons, the final tier of the Acid Rain event becomes unlocked, and you can now acquire Polterplasm from crates.

5. What is the best armor to use against Polterghast in Calamity? Tarragon armor is often considered the best general choice. Lunar armors can also be effective if you’re familiar with Polterghast’s attack patterns. Prismatic armor is another strong choice for mages.

6. What makes Polterghast enrage? Venturing to the Surface will enrage Polterghast, significantly increasing his speed, damage, projectile speed, fire rate, and damage reduction. Stay within the Dungeon to avoid this.

7. When should I fight Polterghast? While you can fight Polterghast before any other post-Moon Lord bosses, it’s highly recommended to defeat Providence, the Profaned Goddess and the Rune of Kos bosses first. This gives you access to better gear.

8. How do I summon the Old Duke? The Old Duke can spawn at the end of an Acid Rain event after Polterghast has been defeated. He appears from a giant sulphurous tornado. Alternatively, he can be summoned by fishing in the Sulphurous Sea with a Bloodworm after Moon Lord is defeated.

9. Can I farm Phantom Spirits to continuously spawn Polterghast? No, the Phantom Spirit method only works once, the first time Polterghast is summoned in a world. After that, you must use the Necroplasmic Beacon.

10. Does Polterghast have any special drops? Yes, besides unlocking the Arc NPC, and abyss loot from the bosses of that biome.

11. How difficult is Polterghast compared to other bosses in Calamity? Polterghast is considered a challenging boss, even amongst the tougher encounters in the Calamity Mod. Its high speed, damage, and projectile spam can easily overwhelm unprepared players.

12. What is the significance of the Dungeon in the Polterghast fight? The Dungeon is the only location where Polterghast can be summoned. Leaving the Dungeon causes it to enrage or despawn.

13. Are there any specific arena setups recommended for the Polterghast fight? A large, open area within the Dungeon is ideal. Clearing out some of the Dungeon walls can provide more maneuverability. Using platforms can aid in dodging projectiles.

14. What class is best suited for fighting Polterghast? All classes can succeed against Polterghast with the right gear and strategy. Ranged and Mage builds often have an easier time due to their ability to maintain distance, but melee and summoner builds can also be effective.

15. How does the Calamity Mod enhance the overall Terraria experience? The Calamity Mod dramatically expands the Terraria experience by adding new bosses, items, biomes, and lore. It provides a significant challenge for experienced players and offers hundreds of hours of additional content to explore. It is a prime example of how modding can transform a game. It also gives players new content to create educational content about.
