What is worth knowing At 41 steps it is longer than 98% of solved elements, which puts it in our marathon band. Only 2 known combinations produce Bupb, so there is very little room to improvise. Follow the path exactly. Bupb is close to a dead end. It feeds only 1 onward combination, so it is more of a collectible than a building block. Its crafting depth of 65 is unusually deep. Depth counts the longest chain needed to reach it, and most elements people search for sit well below this. Full crafting path from the base elements Start with Water, Fire, Wind and Earth, then follow these 41 combinations in order.
