Spatial Relics
by sheeta
Spatial Relics adds collectible artifacts to Fabric for 1.21.1, including the Iron Blade with its Iai Strike and a shield, a smithing template and a Lodestone Anchor.
What it does
The Iron Blade is a melee weapon with a charged Iai Strike. Holding Shift while right-clicking charges it, and releasing the charge aims a forward dash of 4 blocks that ends on the target. During the charge, nearby enemies are slowed, and movement speed rises with the Soul Speed enchantment. A strike that kills a target can spread aggression to nearby mobs of the same type, and the Iai dash can serve as a mobility boost during Elytra flight. A Shadow Drawing Blade variant changes how the strike behaves in darkness and fog, where the strike is constricted.
The Echoing Shield and the Echo Shard Smithing Template extend the collection, and the Lodestone Anchor is a utility artifact that works with lodestones. The mod is built to complement vanilla survival mechanics rather than replace them. It is licensed under the MIT License and is not open source. Files are published for Fabric only, for 1.21.1, and the mod runs on the client and the server, so both sides need it.
