Occult Crest into Typhoon (It helps greatly with Elafrost and the ability cd/dash can come in clutch
1:FireBlossom (scales great with health and helps with trades early)Rush your brimstone as it helps with farming and trades with E
2:Elafrost (Ultimate sticking power and the mana is a nice lil treat 
3:WorldBreaker (super helpful for getting your damage up in fights and 1v1s)
4:Dream Binder/Life Binder (Life Binder for sustain/scale off picks Dream binder if you want to crush souls and truly not let them play the game.
5:dynamo/Stonewall/Tainted Totem (dynamo adds damage to ALL stuns so it combos great with Elafrost plus Riktor is a walking cc machine.) Stonewall if you need some beef to keep up with late game carries, Tainted is a good mix and the bonus to shield can help you not get popped as fast.
Hope folks enjoy this build as much as i have and feel free to leave improvements down below so i can become more of a menace 
MAX Q E RMB and obviously R anytime possible ❤️
