How to Play
Inferno Isolation slow rolls at level 7 for a three-star Kha'Zix, with Lux as a secondary AP carry. This comp has built-in anti-heal from the Inferno trait, so skip anti-heal items you'd normally build.

Early Game
Shen, Amumu, and Vi are cheap early frontline. Play a normal econ opening while banking toward level 7.
Mid Game
Hold at level 7 and slow roll for Kha'Zix copies. When Kha'Zix Evolves, prioritise Executioner and Spellweaver pieces first.
Late Game and Final Board
Kha'Zix and Lux together cover a mobile assassin and a ranged AP threat, giving you two damage profiles behind the same frontline.
Best Items
Kha'Zix wants Hand Of Justice and Edge of Night; Lux runs Spear of Shojin and Jeweled Gauntlet; Fiddlesticks takes pure tank stats plus Crownguard.
Best Augments
Building an Army I and Rolling for Days suit the early roll-down; Heroic Grab Bag and Big Grab Bag support the mid game; Golden Ticket and Call to Chaos close it out.
Positioning
Fiddlesticks, Shen, Amumu, Kennen, and Vi wall the front. Kha'Zix can flank from a forward hex as a mobile assassin.
Flex Units and Alternative Carries
Nidalee is the flexible utility slot.
Strengths and Weaknesses
Built-in anti-heal and two damage profiles give this comp real utility. Its B tier rating reflects a lower ceiling than the top Rival-based picks unless Kha'Zix's copies come easily.
