Explosive Concoction Map Showcase with lvl 15 (~50 level requirement) gems with Elementalist in Blood Aqueducts (lvl: 60 Zone) and a Tier 5 Map + Boss (lvl:72 Zone) with ~ lvl:75 Skill Tree
Clearspeed is decent enough,
Single target is lacking a lot in my opinion and need to wait for updated Path of Building Community Fork for doing proper math.

This build will get a huge buff in 3.16 maybe it is even a good league starter now?!
