There is really a drawback, however. As LiftingNerdBro explains, this is simply not the build you wish to use if you plan to farm bosses. If you're new or even a casual player, don't sweat this, though the lack of decent single-target damage will acquire boss encounters and earn them somewhat of a slog. During the leveling process, this won't matter, but this build is more preferable off for POE Currency general map clearing and farming instead.

Lifting Nerd Bro also features a handy written guide you may reference over within the forums—and yes, he includes some good leveling tips if you are new.
