A 1.18 client side SMP pack that works with any vanilla server, meant for SMPs, designed specifically for the S3K SMP. The pack contains mods to improve fps and your overall experience like sodium (its kinda like optifine) and spark to give you more information about your connection with a server. Theirs also some quality of life mods like shulkerboxtooltip to see a preview of whats in your shulker box and farsight that allows you to see chunks you have already loaded, giving you farsight. The pack also has simple voice chat just in case you want to join a vanilla server that has the simple voice chat plugin.
