League of Legends Rek'Sai Guide: Best Build, Runes, Items, Combos

Rek’Sai is a powerful and mobile jungler in League of Legends, known for her ability to tunnel through terrain, track enemies with Tremor Sense, and burst down targets with lethal combos. With her aggressive playstyle and strong early-game pressure, Rek’Sai excels at controlling the map, catching opponents off guard, and snowballing leads. In this guide, we’ll break down the best build, runes, items, and combos to help you master Rek’Sai and dominate your jungle matchups from start to finish.

Rek’Sai Abilities Overview in League of Legends

Here’s a breakdown of Rek’Sai’s abilities in League of Legends:

Passive – Fury of the Xer’Sai: Rek’Sai generates Fury with basic attacks and abilities while Unburrowed. When she Burrows, she consumes Fury to heal over time.

Q – Queen’s Wrath / Prey Seeker:
• Unburrowed: Her next three attacks deal bonus damage to nearby enemies.
• Burrowed: Fires a straight-line skillshot that reveals and damages the first enemy hit.

W – Burrow / Unburrow:
• Unburrowed: Rek’Sai burrows, gaining Tremor Sense to detect enemy movement and bonus movement speed but reducing her vision range.
• Burrowed: Rek’Sai knocks up and damages nearby enemies, interrupting dashes and combos.

E – Furious Bite / Tunnel:
• Unburrowed: Rek’Sai bites the target, dealing damage that increases based on her Fury—true damage at full Fury.
• Burrowed: Creates a tunnel that Rek’Sai can use to move through terrain. Each tunnel lasts for a few minutes and has a cooldown before reuse.

R – Void Rush: Rek’Sai can only cast this on a recently marked enemy (by auto-attacking). She becomes untargetable and dashes to the marked target, dealing massive damage based on missing health.

These abilities make Rek’Sai an excellent pick for burst damage, map mobility, and strong ganking potential.

How To Play Rek'Sai In League of Legends

Best Summer Spells For Rek’Sai

The best summoner spells for Rek’Sai are Smite and Flash. Smite is essential for any jungler as it allows you to secure important objectives like Dragon, Rift Herald, and Baron, and is required to purchase jungle items. Flash is equally important, giving you a reliable tool for escaping danger, repositioning during fights, or making aggressive plays by flashing into a knock-up with your Burrowed W. This combination of Flash and Smite is standard on jungle Rek’Sai and gives you both utility and kill pressure throughout the game.

Best Rek’Sai Runes

The best runes for Rek’Sai focus on maximizing her early-game aggression, sustain, and ability to snowball from the jungle. Use Precision as your primary tree and Inspiration as your secondary:

Primary – Precision
• Conqueror – Gives stacking AD in fights, great for extended trades and skirmishes.
• Triumph – Heals you on takedown and gives bonus gold, helping with jungle clears and clutch fights.
• Legend: Alacrity – Boosts attack speed, speeding up her clear and improving DPS.
• Last Stand – Increases damage when low on health, which synergizes well with her all-in playstyle.

Secondary – Inspiration
• Magical Footwear – Free boots with extra movement speed, saving gold and time.
• Cosmic Insight – More ability haste and summoner spell haste to help you gank more often.

Bonus Stats:
• Attack Speed
• Adaptive Force
• Health (or Armor if against heavy AD early)

This setup is strong for early invades, aggressive dueling, and fast clears—everything Rek’Sai excels at.

Best Build For Rek’Sai

The best build for Rek’Sai in League of Legends focuses on early aggression, burst damage, and survivability so you can dominate skirmishes and gank effectively. Start with Youmuu’s Ghostblade for lethality and mobility, then rush Eclipse or Stridebreaker depending on whether you want burst or stickiness. After that, build Black Cleaver for armor shred and health, followed by Maw of Malmortius if the enemy has AP threats, or Sterak’s Gage for survivability in extended fights. Finish with Guardian Angel for late-game insurance or Death’s Dance if you’re ahead and want to keep snowballing. For boots, go Plated Steelcaps against heavy AD or Mercury’s Treads for CC and magic resist. This build gives you the burst, durability, and mobility needed to carry from the jungle.

Best Combos To Learn For Rek’Sai

Here are the best Rek’Sai combos to learn that will help you burst enemies, secure kills, and dominate early skirmishes:

1. Basic Prey Combo (for quick trades):
Unburrow (W) → Auto Attack → Q (Queen’s Wrath)
Use this to knock up and immediately deal burst damage. Great for jungle skirmishes and small trades.

2. Gank Engage Combo:
Tunnel (E burrowed) → Unburrow (W) → Auto → Q → E
Start with a Tunnel to close the gap, knock the enemy up, then use your full combo to deal damage.

3. All-In Burst Combo (with ult):
Tunnel (E burrowed) → Unburrow (W) → Q → E → R (Void Rush)
This is your full-damage combo when going for a kill. After your full combo, use R to execute the enemy if they’re low on HP.

4. Disengage or Peel:
Tunnel → Unburrow (W) → walk away or re-engage
Use this to interrupt channeling abilities or peel for teammates.

Practice these until they feel smooth and fast—Rek’Sai’s strength is her ability to appear from nowhere, knock enemies up, and delete squishies before they can react.
