About this project
What does Confluence: infernum add?
Confluence: Infernum
Confluence: Infernum is a massive expansion for the Confluence: Otherworld mod, designed for players who find the base game too easy. Prepare for brutal challenges, complete AI reworks, and a highly unforgiving endgame experience.
To activate all features, use the command: "/infernum"
⚔️ Boss & Enemy Reworks
**Brutal Bosses:* Every boss features completely rewritten AI, massive health pools, increased armor, blinding speed, and devastating damage.
*Enhanced Regular Mobs:* Zombies and Skeletons spawn much more frequently with armor and powerful enchantments. Skeletons and Blazes attack at a significantly higher rate.
*Unique Enemy Abilities:*
* **Zombies:** Can now regenerate their own health.
* **Skeletons:** Fire deadly bursts of multiple arrows (shotgun style).
* **Creepers:** Gain sudden, terrifying speed boosts.
* **Spiders:** Inflict poison and heavy slowness.
* **Wither Skeletons:** Shoot explosive Wither skulls.
* **Blazes:** Launch giant, devastating fireballs.
🛡️ Progression & Rule Changes
* **Infinite Summons:** Custom summoning items are no longer consumed upon use.
* **New Boss Summons:** Added dedicated summoning items for Skeletron, Wall of Flesh, the Wither, and the Ender Dragon.
* **Strict Hardmode Gatekeeping:** The Wither and Ender Dragon are now strictly locked behind the Wall of Flesh. Attempting to summon the Wither in Pre-Hardmode will cause it to instantly crumble. Attempting to enter The End early will immediately teleport the player back.
* **Totem of Undying Banished:** The Totem of Undying has been completely eradicated. It cannot be dropped, held in the hand, or even kept in the inventory.
* **Aggressive water:** Water in certain biomes—such as the Corruption, Crimson, Jungle, and cold biomes—inflicts debuffs on the player.
* **Oxygen deprivation:** At an altitude of over 250 blocks, the player begins to run out of oxygen.
### 🎵 Immersion & Rewards
* **Custom Soundtracks:** Every single boss features a unique, epic music track exclusive to Infernum mode.
* **Custom UI:** The Wither and Ender Dragon receive brand-new, customized boss health bars.
* **Trophies & Advancements:** Earn unique trophies from defeated bosses and unlock a dedicated advancement tree to track your painful journey.
### 📖 The Ultimate Challenge (Boss Rush)
* **The Guide Book:** Includes an in-game guide that provides crucial gear and class recommendations for every boss fight.
* **Soul of Infernum:** After defeating every boss, you can transform your Guide Book into the *Soul of Infernum*.
* **The Boss Rush:** Using this item triggers the ultimate test — a relentless gauntlet where you must fight every boss back-to-back. During the Boss Rush, they possess extreme durability, and almost any single hit will result in instant death.
*Requires **Confluence: Otherworld** to function.*
