Born from the depths of the underworld, Remnants introduces cinematic boss encounters, dangerous undead creatures, and fast-paced combat designed to challenge even the most experienced adventurers. Featuring custom AI, animations, models, textures, sound effects, and music, every battle feels unique and memorable.
Remnant Bosses adds animated boss fights, remnant mobs, legendary weapons, and altar rituals for Minecraft 1.20.1 (Forge + Fabric) and 1.21.1 (NeoForge + Fabric).
Bosses
| Boss | Title | Summon item (default) |
|---|---|---|
| Ossukage | Oni Shogun | Nether Star |
| Kotsukage | Bone Sovereign | Wither Skeleton Skull |
| Umbrakar | Riftmaw Colossus | Echo Shard |
Each boss has a boss bar, multi-phase combat, custom GeckoLib animations, and JAuml-tunable stats. Spawn eggs are available in the Remnant Bosses creative tab for testing.
How to summon a boss
All three bosses use the same Ancient Altar layout. Requirements and pedestal blocks differ per boss (see table below).
1. Craft the ritual blocks
| Block | Recipe |
|---|---|
| Ancient Altar (×1) | 3× Chiseled Deepslate across the top row, 1× Diamond in the center, 2× Emerald on the bottom corners |
| Ancient Pedestal (×4) | 1× Emerald on top, 1× Chiseled Deepslate in the middle, 3× Chiseled Deepslate along the bottom row |
Recipes are shaped crafting; see JEI/REI in-game.
2. Build the ritual
Place one Ancient Altar and four Ancient Pedestals three blocks away on the four cardinal sides. On top of each pedestal, place the boss-specific activation block (one block above the pedestal).
Top-down layout (activation blocks shown; A = altar, P = pedestal):
[pedestal 4 / north]
|
[pedestal 2]—[ altar ]—[pedestal 1 / east]
|
[pedestal 3 / south]
- Pedestal 1 — 3 blocks east of the altar (
+X) - Pedestal 2 — 3 blocks west of the altar (
-X) - Pedestal 3 — 3 blocks south of the altar (
+Z) - Pedestal 4 — 3 blocks north of the altar (
-Z)
All pedestals must be Ancient Pedestal blocks. The blocks on top must match the config for that boss exactly.
3. Activate
Hold the boss activation item in your main hand and right-click the Ancient Altar.
- The activation item is consumed (survival/adventure; creative is free).
- Lightning strikes each pedestal top; the offering blocks are destroyed.
- After a short delay (~4 seconds), the boss spawns on the altar.
- Ossukage also spawns remnant skeleton minions (default: 2; configurable).
Default pedestal offerings
| Boss | Activation item | Pedestal 1 (east) | Pedestal 2 (west) | Pedestal 3 (south) | Pedestal 4 (north) |
|---|---|---|---|---|---|
| Ossukage | Nether Star | Skeleton Skull | Skeleton Skull | Skeleton Skull | Skeleton Skull |
| Kotsukage | Wither Skeleton Skull | Bone Block | Soul Sand | Soul Soil | Nether Wart Block |
| Umbrakar | Echo Shard | Amethyst Block | Crying Obsidian | End Stone | Sculk |
Registry IDs for pack makers:
| Boss | Config file | portal_activation_item |
