PoE Ball Lightning, Lightning Warp, Lightning builds

Most leagues I try to make a unique concept for Ball lightning because I'm obsessed with the skill sadly. Been thinking about this concept before the league launch but didn't realise I'd get rich this league. First time using Progenesis and Mageblood in a build but I am not sure what additions or changes I can make, The only items I have crafted is the boots, the amulet and the wand and I have purchased the body armour and lethal pride already. Ill have about 100divs leftover after purchasing the Mageblood and decently rolled Progen

Hey guys, been trying to throw together a ball lightning starter on elementalist. I've gotten defensives sorted pretty decently for what I'm planning on using it for. Curious if you guys know of anything I could use to amp up the damage a bit more without sacrificing defense aside from 6 link etc.
