Runic Core 1.0.3

Release for Minecraft 1.21.1, NeoForge 21.1.253 and Java 21. Install the same version on client and server. No additional required mods.

Runic Ascension Altar

• New three-block-tall altar directly upgrades equipment beyond normal enchantment levels.
• Includes 40 recipes across 14 enchantments, with a searchable recipe list in the fully unlocked Runic Codex.
• Five-second rituals use one infused crystal charge. A pulsing energy sphere and glowing blue-violet beam connect the mounted crystal to your equipment.
• Preserves item names, damage, compatible enchantments and installed Runic Cores; ascended items receive a blue-purple glint.
• Sharpness and Smite reach level X. Efficiency, Impaling, Power and Bane of Arthropods reach VIII, including VI and VII recipes. Every intermediate ascension level has a recipe; earlier upgrades are optional.
• Feather Falling recipes use feathers and phantom membranes, with no Rabbit’s Foot ingredient.
• Ascension recipes are documented in the Codex; this build has no JEI category for them.

Upgrading and validation

Back up worlds, remove the old Runic Core JAR, and install runiccore-1.0.3.jar. Existing registry IDs and core data formats are retained. New ore generation requires new chunks.

Build and all 85 required server tests passed. Existing legendary abilities, altar awakening, dynamic sockets and equipment fittings are retained. Custom renderers may need adapters or visual fallbacks; universal modpack/shader or independent multiplayer certification is not claimed.
