[LotM V2] Questions about the law of beyonder characteristics

In chapter 323 as klein is reading the formulas on the dark emperor blasphemy card, klein says that due to the law of beyonder characteristics and indestructiability, there can only be 3 sequence 1s in a pathways in the absence of a sequence 0 and 0 sequence 1s if there exists a sequence 0, perhaps i haven't correctly understood the law, but why can there only be 3 sequence 1s at max in a pathway? And how is there a fixated number of beyonder characteristics if you can become a beyonder if have the ingredients for a potion? I tried searching for it but everywhere i go is full of spoilers so i decided to ask here.
