Aethersteel
by NotRoss
Aethersteel, a Forge and NeoForge world generation mod by NotRoss, adds a stronger netherite-class ingot and an upgrade template found in suspicious blocks.
What it does
The mod adds the Aethersteel Ingot, a material described by the author as roughly twice as strong as netherite. It also adds an Aethersteel Nugget and Aethersteel Scrap as intermediate materials. Aethersteel Upgrade Templates can be obtained by mining Suspicious Aetherslate, with a chance-based drop. A template is applied at a Smithing Table together with a netherite tool and an Aethersteel Ingot to produce an upgraded tool.
Armor trims can be applied to armor made from Aethersteel, and recipes can be looked up with JEI or REI. The mod runs on the client and on the server, so both need it. Farmer's Delight and Iron Bookshelves are optional dependencies that the mod can use when installed. The author permits addon mods built on top of Aethersteel. The project is released under All rights reserved, so it is not open source.
