Wanted to quickly go over my league start character because I haven't really seen any other good attempts at this gem, and saw some people dunking on it very unfairly IMO. It's not the strongest build ever, but with decent investment it shines at heist and Maven invitations (running fast and dealing good burst damage is all you need).

Pitfalls: This build is bad if you need to run some content where you'll need to attack for more than 30 seconds straight without killing anything. It also is hard to take higher than 5 million DPS (Primalist version can probably get to 10 milllion with +1 proj charms but that's a different story). It's also not comfortable to map with it for very long because it requires precise aiming, unlike most projectile skills your projectiles will not hit anywhere but the area you aim at. The Reddit thread I mentioned covers some of the other issues with the build (though as I hope the video shows, the skill is still viable). https://old.reddit.com/r/pathofexile/comments/18q4u3q/i_tried_to_make_explosive_concoction_of/
