ISMP S5 Singleplayer & Server Modpack

This is the full ISMP S5 modpack, built around a fantasy and magic theme centered on Enchancement's overhauled enchantment system, with a focus on exploration through custom biomes, structures, mobs, weapon, etc. (you get the point).

What this actually adds:

  • New biomes across the overworld, nether, and end
  • Overhauled and brand new structures and dungeons
  • New weapon types including scythes, katanas, greatswords, battleaxes, and sea weapons (and a lot more)
  • Expanded food and farming through Farmer's Delight and its addons
  • A rehauled Nether and End (End update guys)
  • New mobs from Friends & Foes and other mods
  • New blocks, items, and game mechanics
  • A lot of enchants

Notes:

  • If running on a server, adding server-side performance mods like Lithium is recommended
  • If playing singleplayer, adding client-side performance mods like Sodium is recommended
  • Configs may differ from the live ISMP S5 server
  • While I try to keep this up to date the mods may not always be on the latest version (I try my best ¯_(ツ)_/¯ ).

All mods added (I'll try to keep this up to date):
