Key Strategy Takeaways

  • This is the Unrivaled augment line: field Rengar and Kha’Zix together only when the augment and current game state support the pair.
  • Patch 18.3b reduced Kha’Zix base and isolation damage, so current community guides rate the reroll as conditional rather than a reliable force.
  • A high-item opener matters; itemize Rengar early, then give Kha’Zix a useful damage and survival package and protect the Hecarim frontline.
  • At Level 7, stabilize before slow-rolling; stop chasing three-stars when contesting, health, or the shop makes the cost too high.

What Is the Unrivaled Rengar and Kha’Zix Comp?

The Rengar and Kha’Zix TFT comp is a Set 18 three-cost reroll line built around the Unrivaled Augment. It lets you field the Rival pair and rewards their interaction, but that does not make the board an automatic play whenever you see either champion. The Augment, items, early copies, and frontline all need to line up.

This distinction matters on Patch 18.3b. Riot reduced Kha’Zix’s base ability damage from 285/400/580 to 265/370/535 and his isolated-target damage from 310/445/660 to 285/410/605. The current TFT Flow Unrivaled guide lists the line as C tier after the patch update, while TFT Academy’s current guide calls it conditional. These are third-party assessments, not a TFTFans win rate; the useful conclusion is to check your spot before committing.

This is a champion-specific page for Unrivaled. Our general TFT reroll guide covers the wider reroll decision, and the two-cost reroll guide covers different carries such as Yunara, Caitlyn, and Warwick.

Unrivaled Board: Rengar, Kha’Zix, and a Real Frontline

The reroll core is the pair plus a tank that can buy time for both carries to reach their targets. Hecarim is a common three-star frontline target in current guides, but use another upgraded tank when that is what the shop gives you. At Level 8, add the strongest useful trait or utility unit rather than holding a weak slot for a fixed screenshot.

Unit or roleBoard jobPractical rule
RengarPrimary item holder and melee carryCurrent TFT Flow guidance recommends itemizing Rengar early; his takedowns help the board keep pace
Kha’ZixBackline access and isolated-target damageWatch the enemy formation and aim him toward a target with no adjacent allies when possible
Hecarim or another upgraded tankMain frontlineGive the tank enough durability to buy casts; do not spend all components on the two carries
Flex unitsTraits, utility, or stronger late-game unitsKeep the units that improve the fight you are about to play; replace weak slots as you level

Kha’Zix’s target condition is part of the positioning plan: his ability deals extra damage and restores mana when the target has no adjacent allies. Scout before each fight and look for a carry or other valuable unit that has been left alone. If the opponent changes sides or groups the backline, move your board rather than expecting the same jump to work again.

Items: Build Rengar First, Then Finish Kha’Zix

The current community builds agree on a practical priority: make useful items early, and usually finish Rengar before Kha’Zix. TFT Flow lists Titan’s Resolve, Edge of Night, and Guinsoo’s Rageblade among Rengar’s core options; for Kha’Zix it lists Edge of Night, Hand of Justice, and AP damage such as Rabadon’s Deathcap or Jeweled Gauntlet. Treat the list as directions, not a rigid recipe.

HolderUseful directionWhy it matters
RengarTitan’s Resolve, Edge of Night, Guinsoo’s RagebladeGives the first carry damage and enough survival to keep contributing
Kha’ZixHand of Justice or another flexible damage item, plus AP or protectionHelps him convert a good target into a takedown after the 18.3b damage cut
HecarimGargoyle Stoneplate, Warmog’s Armor, or other effective tank itemsA durable frontline prevents the reroll pair from being the only units expected to absorb damage

There is a real component trade-off here: a bow can become Rageblade or Titan’s Resolve, while a chain, cloak, or belt can help finish a frontline item. A sword or glove can go toward Edge of Night or Hand of Justice. Slam an item when it improves your Stage 2 board and still has a plausible home. Check recipes in the TFT item matrix and compare holders in the item guide.

Level 7 Reroll Plan

Do not roll just because the Unrivaled Augment appeared. First confirm that the board can reach Level 7 without losing too much health, that you can itemize at least one carry, and that the lobby is not already holding most of your copies.

Stage or stateWhat to do
Early gamePlay the strongest board and slam an item that can later move to Rengar, Kha’Zix, or the frontline
Before Level 7Keep relevant pairs, scout for contesting, and protect enough gold to search
First Level 7 rollUpgrade the board and frontline first; set a gold floor rather than rolling to zero for a missing carry
Stable at Level 7Rebuild toward 50 gold and slow-roll for Rengar, Kha’Zix, and the frontline target
Low health or nearly complete upgradesSpend more aggressively when the next loss would end the game or when a small number of copies completes the board
After the three-star coreLevel to add a useful unit if the board is already stable; otherwise keep improving the fight at Level 7

TFT Flow’s current 3-cost reroll plan recommends stabilizing at Level 7, then rebuilding economy for slow rolls; TFT Academy likewise describes the line as conditional. Use the shop odds calculator for cost odds, then apply the champion pool guide to account for copies held by opponents. The displayed odds cannot make a contested shop behave like an open one.

When Should You Skip or Leave the Comp?

Warning signBetter response
You do not have UnrivaledDo not treat this as the same board; keep playing your strongest normal line
You cannot make an early useful item for either carryKeep the Augment’s flexibility and look for a different board rather than waiting on ideal components
Several players hold Rengar, Kha’Zix, or HecarimRaise your stop threshold and avoid a long three-star chase
Kha’Zix cannot reach a useful isolated targetChange positioning; if the lobby keeps denying access, value the board by its actual fights rather than a guide screenshot
Your frontline is collapsing before the carries actSpend on the tank or pivot to a stronger upgraded frontline
Patch data or current guides move the line downReassess; do not keep forcing an old ranking after balance changes

The current Riot Patch 18.3 notes are the source for the 18.3b Kha’Zix changes. The exact balance can move again, so check the live patch and your own shops before treating this as a current recommendation.

Rengar and Kha’Zix TFT Comp FAQ

Do I need the Unrivaled Augment?

This guide is specifically for the Unrivaled Rengar/Kha’Zix line. Without that Augment, do not assume the same pair and reroll plan applies.

Is Unrivaled Rengar Kha’Zix still playable after the 18.3b nerf?

It can be playable when the Augment, items, copies, and frontline align, but the answer is conditional. Riot nerfed Kha’Zix’s base and isolated damage, and current third-party guides downgraded the line. Do not force it from a weak opener.

Which carry should I itemize first?

Current TFT Flow guidance favors Rengar first, then Kha’Zix. The best exact items still depend on components and the current patch; a useful early slam can preserve health while you wait for the rest of the board.
