This modpack expands Minecraft to a whole new level with exploration, technology, magic, combat, and much, MUCH more. It is indianajmh's go-to modpack.

Indianajmh's Modpack 2 is a recreation and improvement of the original, with more mods and better performance.

Some of the more prominent mods are:

AppleSkin: Shows how much hunger food gives and a lot more in a nice and fancy way.

Applied Energistics: Adds lots of technologies and complicated energy systems.

AtomicStryker's Battle Towers + Infernal Mobs: Towers that are filled with mobs and loots. Rarely, mobs will be infernal mobs that have special abilities and are very powerful, yet drop great loot.

Aquaculture 2: An awesome water mod that adds fish and other things.

ArmorPlus: Extends Minecraft even further with new gear, however it is very expensive and grindy.

Bibliocraft: Adds working bookshelves, lanterns, and more.

Construct's Armory + Tinker's Construct: A complex foundry system to forge tools and armor of different sorts.

Draconic Evolution: Complicated technologies of a higher tier than vanilla.

Dungeon Tactics: Adds tons of new weaponry, utilities, magic, and more.

End: Reborn: Recreates the end in a much more interesting and different fashion, adding more sets with it.

Flexible Tools: A set that is around as good as diamond that cannot be enchanted, but can be upgraded to become very useful.

Hardcore Darkness: In dark places, it isn't just a little dark, it's pitch black, which is why dynamic lighting from Optifine comes in handy.

Ice and Fire: Dragons: A huge extensive mod that adds fantasy to its finest, with powerful dragons, cyclopses, and much, much, more.

Iron Chests: Lots of new chests that make it easier to store things.

MrCrayfish's Furniture Mod: Tons of new furniture for recreational use, especially toilets.

Mystical Agriculture + Agradditions: Agriculture except you can farm what you need, such as diamonds and other materials, but can take time to accomplish.

Nether Update Backport: Brings the nether update back to 1.12.2.

Potion Core: Tons of new potions to add a huge variety.

Realistic Terrain Generation: Terrain generation that is both more realistic and satisfying.

Reskillable: You want to use iron? TOO BAD. You have to get experience to be good enough. (Basically it just adds skills that you can improve with XP that also limit the use of certain sets until a certain skill level is achieved.)

Spartan Weaponry + Spartan and Fire: Tons of new weaponry over many different set that are compatible with many mods, such as Ice and Fire: Dragons.

The Midnight: A mysterious and scary dimension for you to explore.

The Twilight Forest: A classic dimension mod that adds new sets, bosses, and much more to explore and discover.

Tree Chopper: Allows you to cut down trees completely with an axe.

Vic's Modern Warfare Mod: Guns, bombs, and much more in this modern warfare mod.

YUNG's Better Caves + Mineshafts: Improved cave generation along with better mineshafts.

These are only some of the mods in the modpack, there are 86 in total!
