You may notice that there are no seperate chapters mentioning ChromatiCraft. This is done to keep the feeling of ChromatiCraft, which has it's own guide which you should follow.
Just know that if a ChromatiCraft item is required, and you can't craft it, you should progress more in ChromatiCraft.

The same thing goes for Forestry, no seperate chapters for it seeing as it isn't gated at all. Some tips:
 -Power can be done with a few Extra Utilities generators, or one of the various other more magical options, like the mana fluxfield or the aura cascade fluxing node.
 -Your goal is to get Transmuting Combs and Enchanted Drops, though other bee products can be used to skip past some resource gates.
 -The ChromatiCraft bees have amazing traits, and can help you get some of the more annoying ChromatiCraft resources.
 -Use frames, Soul Frames for mutations, Oblivion/Lifecycle Acceleration Frames for faster lifecycles.
 -If you can, get a Lumen Alveary Booster. They should help a huge amount.
 -There is a special bee that can make Ichor. It's extremely hard to breed though. There are also bees for celestial pearls, eldritch eyes, and more. Take a look at recipes to see if there is a bee that can get the item.
