SCP-148, Telekill

The mod draws on the SCP universe, where the material is known as Telekill, an anomalous metal found deep underground. Its ore generates between Y-levels 10 and -64 in the overworld, and only a Netherite pickaxe can break it, which takes a long time. Smelting the ore in a blast furnace yields Telekill Scraps, and a smithing table combines them with diamonds, iron and copper into Telekill Ingots and Telekill Blocks. An ingot can also upgrade Netherite equipment and shields.

The items are strong but unpredictable. Telekill tools have high efficiency and high harvest levels, yet they degrade quickly, and using one can occasionally inflict a short bad effect on the player. The Telekill sword deals 80 damage and often kills a creature in one strike, with limited durability. The mod was made with MCreator and requires Geckolib to run, and it runs on client and server, so the server and every player need it. The license is All rights reserved, so the mod is not open source.
