The Clapped Individuals Pack is a pack originally made for a few friends to mess around on a multiplayer server, no quests, no "way to play", just a bunch of fun mods thrown together.
Some of the core mods added to spice up you're multiplayer include:
Simple Voice Chat: A Proximity chat mod allowing you to communicate with your friends in-game
Ballistx: Nukes, bombs, explosions all powered by the Electrodynamics mod/energy system
Ice & Fire: Tame and defeat dragons!
And many quality of life/small game improvement mods!
