ForgeNeoForgeClient and serverMIT License1.20.1 – 26.2

What it does

The mod adds extra slot cores that increase the number of Curios slots a player has. Obtaining them needs Curios API, which is required and must be installed alongside the mod. Five colors of core are added in total, and some of the Curios items can be combined with a core to gain a slot.

Both the server and every player need the mod, since it is set up as client and server. Files are published for Forge and NeoForge, for the 1.20.1, 1.21.1, 26.1.2 and 26.2 game versions, with 1.0.1 for 1.20.1 as the latest Forge file and 2.0.0 for 26.2 as the latest NeoForge file. It is released under the MIT License and is not open source.
