This is a guide to Sivir, the Battle Mistress.

Time and time again I have found that this build works best for me, with a twist here and there for different opponents / teamsetups.

This guide will help you through facing most games.

A quick note for up ahead:

I know the items in the build are too many.
Some of them are interchangeable:

-Last Whisper -or- Black Cleaver
-Frozen Mallet -or- Stark's Fervor
-Aegis of the Legion -or- Banshee's Veil

My runes consists of ArP/Mp5/Mp5/ArP runes.

Marks are Armor Penetration, the best runes for any physical carry end-game.

Seals are Mana per 5 regeneration, these will sustain you enough early game and will grant you plenty of mana to live without a Manamune or Chalice.

Glyphs are also Mana per 5 regeneration, same reason as Seals.

Quintessences are -just like marks- also Armor Penetration.
~These can be replaced with Flat Health quintessences if you are a novice player~

My Masteries are not a standard 21/0/9 build.

This is because Sivir does not need the additional Critical Strike damage, nor the flat +5% damage bonus. What she does need is more Mana Regeneration and more Movement Speed (she's quite slow)

Basically everything she wants in the low Offensive tree is taken. The ones we care most about are:
-Alacrity: +4% Attack Speed (noticable early game, but devastating late game.
-Sunder: +6 flat Armor reduction (stacks with your Marks/Quints and allows for some serious damage, even on tanks!)

The ones we care most about in Utility are:
-Awareness: +5% experience bonus (outleveling your opponent and racing to level 9 allows you to literally take one third (1/3) or even half of your opponents health with a single Boomerang Blade. These also allow you to dominate early teamfights more easily.
-Meditation: 3 mana per 5 seconds. Good. We like mana. But we hate building items for mana.
-Quickness: +3% movement speed. This allows you to stay on top of the movement speed late game, and also help you dodging skill shots early game.

You start off with a Doran's Blade and CLAIM!!!! mid-lane.

When you are not being harassed often, and it's easy to farm then just stay farming and don't return for a second Doran's Blade.

If you are being harassed alot however, recall asap or when your opponent recalls.

Your second item should be an instant Berserker Greaves, or if you farmed well enough and didn't need a Doran's Blade early on you CAN go for a 10-minute B.F Sword which allows you to dominate your enemy with your Q.

From there on you follow the build as specified. Note that if Frozen Mallet is interchangeable with Stark's Fervor if your team has more benefit from it (for example, you have a Xin Zhao or Tryndamere in your team) and if you are not being focused.

The Banshee's Veil may be shunned upon by some people, but in my opinion it is still on of the best Magic Resistance items in the game. Even for Sivir.

The reason for this is that this allows you to build Berserker Greaves at all times, and even allows you to stay in the fray and avoid deadly stuns/suppresses which can almost kill you outright in a teamfight if your positioning is off.

However, if you simply cannot stand the thought of having Banshee's on Sivir, i suggest you take either Aegis of the Legion or you take Wit's End and take Mercury Treads.

Last Whisper is one of those items that will allow you to destroy the enemy tank.

But note, Last Whisper only beats Black Cleaver if at least 2 of the enemies have at least 140+ armor. So if they only have 1 tank, get Black Cleaver. Or if they have 2 off-tanks with around 120~ armor, get a Black Cleaver.

I like Last Whisper better though, because it provides max benefit instantly, whereas Black Cleaver can fall off. Black Cleaver DOES provide some more AD and AS though.

At level one you start with your Boomerang Blade.

When you approach mid-lane try to hit your opponent with it as soon as possible. Last hits should be done manually up until at least level 5.

At level 2 you put one point into Spell Shield, allowing you to catch spells and actively regain mana - and returning the favor by your new mana with a Boomerang Blade right into the face!

Level 3: Boomerang Blade. More damage. Try to overlap your harrassing Q with a minion kill or two. Don't choose one over the other, try to position yourself to do both with a single Q. Even if this means reduced damage on the enemy, it's still damage and makes them fear you slightly because they will realize you know what you are doing.

A big no-no at this point is to throw your boomerang straight to a fresh minion wave resulting in mana loss, no minion kills, and only around 10-20 harassment damage. JUST DONT DO IT!!

Level 4: Get a point into Ricochet. But do not leave it on at all times. You only want to turn it on if other minions are low health, or if the enemy champion is near enough to possibly take damage from it. Your next point will be in it at level 8, because you simply do not deal enough damage yet to reliably grant you additional minion kills.

Only use Spell Shield if you see the missile already in flight!!

If you are facing an opponent such as Lux or Ashe you can deliberately walk into their spells and refund your mana. Beware though, that if you do this too often they will realize what's going on and try to hit you with another spell right after you absorbed their first spell - because they know your Spell Shield is down at that point.

Level 5: Now your Glyphs and Seals allow you to throw your Boomerang Blade alot more often. You can take down around 3 half-health minions in a single toss (expecting no additional damage loss from more minions, and expecting a hit on both the throw and the return)

Level 6: Now at this point you should have your opponent pretty scared or even recalled once or twice. If they have, this is a perfect moment to push. Put on your Ricochet (W) and simply knock over those minions. Then when you reach the tower there should be no minions nearby and you HAVE to land a double-hitting Boomerang Blade and avoid a tower hit. This will set alot of pressure on your opponent almost always forcing them to go back. If they do, pop your Ult and damage it as much as you can (take off Ricochet if enemy champ is near, or if no minions are near). When your Ult has around 5-6 seconds left, run the hell back to your tower and recall or kill the wraiths near your tower.

BE CAREFUL FOR JUNGLERS / MIA CHAMPIONS

Level 7: Boomerang Blade.

Level 8: Either Ricochet if it's easy, or Spell Shield if you're having a hard time.

Level 9: Boomerang Blade. It will hurt now. A lot. Seriously. Make 'em QQ about nerfs for taking 1/2 of their health. (You should have a BF sword at this point btw)

The rest is up to you.

If it's easy, go for more Ricochet. If it's hard, or with a lot of CC go for some more points at Spell Shield.

Remember, no game is the same.

I prefer Flash and Teleport.

Flash because it can mean an instant GTFO card, positioning or even a gank with Flash-Boomerang-ult-autoattacks.

And Teleport because you are the Goddess **** Empress of Pushing and Backdooring.

Teleport is interchangeable with Ghost if you prefer it, but I simply think that Teleport suits her better, because she doesn't have a reliable slow or gap-closer anyway (unlike Tristana, Ashe and MF)

If the Tank is A, you are B

Clearest rule of all: STAND THE **** BEHIND THE TANK

You will die near instant if that Stun/Suppress lands on you. And Champions like Jax, Katarina, Xin Zhao are your worst enemy.

Your job is to press R at the correct time, and simply throw a Boomerang Straight through them (avoiding the tank to prevent damage reduction) and auto-attack your way to victory. Your Ricochet will deal a metric ****ton of damage and should wreck an enemy team in no less then 10 seconds.

Remember. Sivir is made or broken with positioning. EVERYTHING LIES ON POSITIONING.

You want to Auto-attack as much as possible, as safe as possible.

A 100 damage hit turns into a 330 hit instantly if you can hit all 5 champions with Ricochet.

That means a 400 damage hit (which you will do on squishies late-game will auto-magically deal
1220 AOE damage. And you seemingly deal a hit 2 and a half times per second with your Ultimate (or every 0.4 second), meaning you will deal a mathematical @#%(&*@$^*****%(*&)%%@*_))(YOU&*%*^&$$%^&*ASHE*^&$^@#*(&) of damage.

I like Sivir alot. And i think people underestimate her capabilities.

I agree that she isn't Ashe, Tristana or even Miss Fortune and lacks a single target nuke or a GTFO button, but she makes up for that with her insane farming skills (meaning you are required to be fed in order to be viable (MF MUCH)) her great AOE damage and one of the best ultimates in game.

I hope you found this guide helpful in some way and would love to hear any criticism or comments.
