FTB Teams Mod — Reference
Items and Blocks
FTB Teams is a utility and library mod; it does not add any physical blocks or items to the game world. All of its functionality is handled through the GUI and the command system. It does not add new mobs, biomes, or dimensions.
If you are looking for team-based blocks (like the 'Team Assembly Table' or 'Claiming Tools'), those are provided by companion mods such as FTB Chunks or FTB Quests, which utilize the FTB Teams API to function.
