The second of the ten mods every pack on 1.12 should install, no questions asked.

The vanilla item id limit can be reached by installing a single mod in some cases. Bring the power of The Flattening to your instance and forget this problem ever existed with REID.

CraftTweaker is a powerful packdev tool, and this addon expands that capability tremendously with targeted improvements that fill in critical gaps in the base functionality.

The first of the ten mods that every pack on 1.12 should install, no questions asked.

A truly staggering number of fixes with a robust configuration system.

Nothing more or less than a complete redesign of terrain generation to be a series of sky islands rather than the traditional Minecraft experience.

Like the original pack, it suffers from Fetch Quest Syndrome, has critically poor modded dimension integration, and the last chapter isn’t worth it; however, the new terrain challenges add an additional layer of complexity that make it a fun experience nonetheless.

When people talk about 'integrating mods into a pack', this is what they mean. Instead of "hey, you just unlocked Blood Magic, go play that for four hours until you get this item", this pack says "hey, you just unlocked Blood Magic, go grab these items from these other mods so you can use Blood Magic to make this item from a different mod so you can progress a little further in a third mod", and it does this for every mod.

Performance suffers a little whenever a complex CraftTweaker script fires, but this only happens on Age transitions, so just grit your teeth and then revel in your newfound power.

The last chapter isn’t worth your time, and mods like the Twilight Forest aren’t so much integrated as they are used as a rudimentary time gate, but overall the experience is solid.
