My playstyle with this build is trying my best to win during the laning phase and abuse viscouses incredibly strong base scalings to almost one-shot anyone for the first 20 min of the game, then since Viscous starts falling off as a damage dealer by around 30 min I slowly transform into a Brawler / Tank / Disruptor
Get this after if you have flex slots
[25 + min] Late-Game , Sell Mystic burst for Rapid Recharge, Spirit strike for improved CD if no flex slot
Trade Enduring Spirit for one of these
Rush this into your second or thrid flex slot
Sell Withering Whip and Quicksilver for these
If the game lasts that long trade silence or KD for Curse and your 1.250 green for rebirth
If you somehow managed to buy ALL of previous items can consider these but you wont be able to afford it in 99% of the games
