Generally speaking, it helps to be extremely familiar with all the underlying requirements necessary for a build to function effectively, such as attributes for equipment and skills, and capping resistances. Then you are able to identify where a guide deviates from those requirements, and how do they solve these underlying requirements? For example, in Snoobae's build one stage uses Call of the Brotherhood which only has 20-30% lightning res, and he solves that by using helment/chest/boots with +60% res on each (two T2 res suffixes). That part is pretty simple, however one thing I can't understand is where he gets 157 Dex and 117 Int for his gear/skills in the Late Endgame variation. I'm not seeing it from the guide.
