Black Sun Red Moon

Quickstart

1. Load any world — the mod activates immediately. The sun turns into a black disc and the moon glows blood-red. You are already in danger.
2. Find the Red Omen Tree that spawns near or on you. Avoid touching it — its leaves inflict nausea and disturbing visual effects.
3. Look up. Floating cube-like Sun Creatures and Moon Creatures will begin hunting you. Kill them to collect Sunnite and Lunite — your core crafting materials.
4. Place Sunnite and Lunite blocks in hollow 2×3 portal frames to open dimensional portals, or combine both materials to open a space portal leading to the final arena.
5. Prepare gear, food, and shelter before entering any portal — the realms beyond are immediately hostile.

Overview

Black Sun Red Moon transforms the Overworld into a cosmic horror setting from the moment you load in. The sky is wrong, the villagers are dead, and unseen forces have marked you. Combat and progression revolve around collecting two rare materials — Sunnite and Lunite — from increasingly dangerous floating enemies, then using those materials to build portals into hostile dimensions and ultimately confront the Massive Black Sun and Massive Red Moon bosses.

How To Use

The Red Omen Tree

A Red Omen Tree (Red Omen Log + Red Omen Leaves) generates near every player on spawn. Its leaves apply nausea and trigger a disturbing HUD vision — glowing red eyes appear at the edges of your screen when the effect is active. Treat the tree as a landmark and warning: combat is about to begin.

Collecting Sunnite and Lunite

Sun Creatures and Moon Creatures are floating, glowing cube enemies that spawn and pursue players in the Overworld. Killing a Sun Creature drops 7 Sunnite; killing a Moon Creature drops 7 Lunite. These items are also placeable as solid blocks. They are your primary crafting currency for everything that follows.

Building Portals

Arrange Sunnite or Lunite blocks into a hollow 2×3 frame (like a Nether portal but smaller) to create a portal to the corresponding floating realm. Using a mix of both materials opens a space portal leading to the final circular Sunnite/Lunite arena. Each portal automatically creates a return link so you can retreat to the Overworld.

The HUD Vision

When the Red Omen effect is active, two pulsing red eyes are drawn on your HUD. This is a visual warning — the effect is tied to proximity or contact with Red Omen Tree leaves.

Abilities And Mechanics

• Black sky: The sun is replaced by an inky black disc; the moon glows red. This is purely visual but sets the tone permanently.
• Rotted Corpses: Villagers in villages are replaced by Rotted Corpses — zombie-type enemies that do not burn in daylight, making villages dangerous at all times.
• Fireproof enemies: All mod enemies — Sun Creatures, Moon Creatures, Sunmen, Moonmen, bosses, and minions — are immune to fire damage.
• Boss drops: The Massive Black Sun drops 32 Sunnite and the Massive Red Moon drops 32 Lunite on death, fueling further crafting.
• Portal return links: Every portal you open creates a reciprocal exit so you are never permanently stranded in a dimension.

Progression And Strategy

1. Early game — survive and farm cubes. Sun Creatures and Moon Creatures spawn in the Overworld. They are your only source of Sunnite and Lunite before portals. Kill them carefully — they are fast and hit hard. Build up a stockpile.

2. Mid game — enter the Sun or Moon realm. Build a 2×3 Sunnite frame or Lunite frame to open a portal. Inside you'll face Sunmen/Moonmen (durable zombie-types) and Sun Ophanim/Moon Seraphim (stronger floating cubes). Scavenge the unique wood types (Sun Tree, Moon Tree) and their Eye blocks while fighting for survival.

3. Late game — open the space portal. Combine Sunnite and Lunite blocks in a 2×3 frame to open the space portal. The arena beyond contains the Eclipse God as a gatekeeper and both the Massive Black Sun and Massive Red Moon as the final bosses. Both have nearly 400 HP and 95% knockback resistance — bring your best gear.

4. After the bosses. Each boss drops 32 of their respective material, giving you a large supply to build, decorate, or open additional portals. The cycle continues — return links let you move between realms freely.

Tips:

• Barricade your base early. Rotted Corpses replace villagers and roam freely day and night.
• The Red Omen Tree cannot be fully avoided on a new spawn, but you can chop it down — just be quick to avoid the nausea effect from the leaves.
• Sun Ophanim are faster than Sun Creatures; Moon Seraphim hit slightly harder than Moon Creatures. Bring a ranged option for dimensional content.
• Knockback barely affects the two final bosses. Position yourself carefully and use sustained DPS rather than knockback tactics.
