🎮 Gameplay

The Three Devil Eyes

* configurable

You'll find the eyes in chests (via loot-table injection) or as mob drops from hostile mobs in the matching dimensions. Throw the eye and an animated portal will open at a safe spot near you — and the fight begins.

Waves, Waves, Waves

• Easy (Overworld): Zombies, Skeletons, Spiders, Witches, Pillagers, Creepers …
• Medium (Nether): Piglins, Magma Cubes, Blazes, Wither Skeletons, Hoglins, Ghasts … (+20 % HP, +10 % damage on mobs)
• Hard (The End): Endermen, Phantoms, Shulkers, Evokers, Ravagers … (+70 % HP, +35 % damage — pure pain)

A short breather is granted between waves. An animated boss bar shows wave progress, remaining mobs, and portal status in real time.

Reward & Punishment

• Victory: XP + random items from a configurable loot pool (Easy: Diamonds, Emeralds, Ender Pearls — Hard: Netherite Ingots, Dragon's Breath, Totem of Undying, Elytra chance, Netherite Smithing Template)
• Defeat: Status effects like Weakness, Slowness & Mining Fatigue

❓ FAQ

Does the mod work with other mob/loot mods? Yes. Chest loot injection uses the standard Fabric loot event, and you can add loot tables from other mods as spawn sources for the eyes.

Do players need the mod on the client too? Yes, for the portal renderer and boss bar animations.

How do I change the configuration? Directly via the /doom command in-game (recommended), or by editing config/gateway_of_doom.json and running /doom reload.

Can I completely rebuild the waves? Yes — define your own mob lists per wave, change timers, HP/damage boosts, and rewards. You can turn Easy into a nightmare or Hard into a tutorial.

Have fun surviving — if you can. 💀
