Electrocute. (Recommended)
- Electrocute adds to the powerhouse level of Lee Sin. It allows him to be rewarded with executing fluent combos. Even if it's a Sonic Wave -> Dragon's Rage -> Resonating Strike, it will still go off, increasing your damage output and burst power. It will make enemies afraid of you, but before they can be afraid at your presence, they're already dead.
Dark Harvest. (Recommended)
- Alternatively, if you're excelling at farming in your Elo, try Dark Harvest. Considering most of my recommended items in this build revolve around an Auto-Attack, you can incorporate it into many combos! Such as; Sonic Wave -> Resonating Strike -> Stealth Ward -> Safeguard -> Dragon's Rage -> Auto Attack. It's important to know that you can always sneak in that Auto Attack when you use Dragon's Rage. Or, for a more simpler approach, you can utilize the Auto Attack after doing a simple Sonic Wave -> Resonating Strike. If you have Duskblade of Draktharr and Dead Man's Plate, it will do even more damage! The only issue regarding Dark Harvest is the loss in early damage. You do have to farm a lot or get ample kills in order for it to help you, though it can help with some of that "Lee Sin falls off late game" bologna. I'll get into the theory behind that later in the guide. It's a lot to write. Lmao.
Predator (Not Recommended)
- Yikes. While you can pair this with Celerity and Waterwalking to deal a fair amount of damage, you lose some of the Early Game potential that you can achieve with Dark Harvest or Electrocute. It's fun to fly around the map at incredible speeds, but it raises a slight aggression in your overall mindset. Once you go into a 1v5 with your team trailing behind you with the build I give, you're not really going to make it out alive, unless they have minimal CC, you have a Stealth Ward, and a safe place to Safeguard to. If you don't pair this with the Celerity and Waterwalking runes aforementioned, your Early Game Scuttle Crab bout that you should strive for becomes nil. (See below for Gameplay/Clearing/Every-Game-Goals)
Hail of Blades. (Recommended)
- You're probably asking why I don't put this under "Not Recommended" as it doesn't have much to do with Lee Sin's playstyle. You're right, but the potential it has is something notable. Early game, Hail of Blades is wonderful. It can put your Attack Speed up to 1.47 In combination with your passive, Flurry. Early game, getting those 3 attacks in with the inclusion of a Red Buff, it allows some leniency for the Laner(s) you're ganking. Here's a scenario of what I mean;- Say your top laner is an Amumu, who doesn't necessarily have the strongest of damage early game, but you want to get a gank off. The enemy top laner is a Garen, who starts out with 616.3 HP before Runes and Items. Let's say his rune path is Grasp of the Undying, Demolish, Chrysalis, and Unflinching in the first tree, and Triumph and Coup de Grace in the Second Tree. He bought Doran's Shield and 2 Health Potions, so that puts him at 761.3 HP Hail of Blades substitutes for what Dark Harvest and Electrocute can't achieve during the early game, making it a great starting tool to snowball your laners even better. Dark Harvest can not give you the damage output to secure the kill for yourself or your Amumu, and Electrocute does 50 damage after you hit all of your abilities, which is not ensured, as opposed to 55(3) you can achieve with those lightning fast Auto Attacks. (I say 55 due to Garen's base armor being 36, and Lee Sin's base damage being 69.2). The only "problem" is if Garen uses Flash to escape, though that's not really a problem, since it ensures another gank within 3 Minutes.

Press The Attack. (Not Recommended)
- While Press the Attack has some Serious early game potential, you're losing out on some of the more valuable asset usage in Lee Sin's kit, and replacing it with chains of auto attacks that attack really slow, unless you're chaining abilities together properly. Even if you have the 40% Attack Speed from Flurry, it's taking the need to burst people down, and instead making it so you have to rely on your Auto Attacks early game to do most of your bidding. Without the Press the Attack proc after a 3rd auto attack, someone like Rengar or Kha'Zix will already have you mincemeat by the time it's begun, since you won't have that extra bit of sustain from Resolve. If you choose Domination as your secondary set of runes, you'll have to choose between Sudden Impact, Ingenious Hunter, and Eyeball Collection, all of which are pretty helpful in destroying targets you choose to pick.
