This modpack's main selling point is MrCrayfishes gun mod with the NineZero's gun expansion addon.
Craft a workbench to create weapons of mass destruction (guns)
It also has apotheosis, making armor and tools super duper busted if you know how to use it. (It also makes the enchantments for the guns super busted but shh)
(This pack also comes with Lootr making it multiplayer viable)
If you have any mod ideas to add here, add them into the comment section and I will view them.
