This is the biggest research tree in the game. It's intended for very high power players, 1 billion in power or more. At high levels, some of the research takes thousands of days.
The major research sections in the Crafting category are the Core Mastery and extra Pieces, Crafting Refinement, Relic and Core Gem Slot, Normal Gear Gem Slot and miscellaneous crafting research. These allow the player to "purchase" and unlock new core gear and a 4th gem slot when they reach a high enough academy level.
