Predecessor Builds > Serath > Serath Jungle (build it thank me later)
Pretty confident that as of v0.18 that this build is the nut. The first 4 items are the core and allow you to chain kills with instant non ult cooldowns and sustain. There is an argument to be made that Overlord is also flexible for your prefered item to help with jungle clear like Skysplitter for example (maybe better as the lifesteal will keep your bar up when clearing in the early game) but as of now I prefer Overlord until further testing. The last two item slots you can build more dmg or sustain depending on enemy team comp, e.g. Basilisk/Citadel. The addition of penumbra, while on the surface seems like a win more item, it will in conjunction with the 70% reduction from fallen grace, intantly refresh non ult cooldowns on takedowns. This build works well for chaining abilities in 1vX situations and even better in team fights as fallen grace and penumbra both trigger on TAKEDOWNS not just solo kills. The move speed from Ortis and Heresy allow for insane gap close and also emegency escape (dont forget to stack Ortis as it also procs on takedown). This build can easily snowball from behind with one good engagement and Ortis stacks. You're gonna love it. THEY WILL KNEEL!
