[2.1a] Camille Guide - "Know your place!" - Guide for mastering Camille

You can easily poke him with the first skill Precision Protocol  after Garen used his silence and wait for your jungler to come and use your The Hextech Ultimatum  to secure the kill, but you can't really solo kill him because of his nature tankiness and his Courage and if you get hit by many of his Decisive Strike and Judgment combo, you might get solo killed instead with his execute ult Demacian Justice *Early Executioner's Calling build is recommended*

Do what every baron laner is supposed to do against Nasus >> Freeze his lane, hit him when he walk up for the minion, and repeat, but don't get poked too hard by his Spirit Fire because Nasus players currently like to max Spirit Fire and don't trade with him when he uses Wither on you and use his Fury Of The Sands to chase you down

you can easily poke his barrier from Way Of The Wanderer off by using your Tactical Sweep and then engage because you will have the barrier advantage from your Adaptive Defenses on him, and his Steel Tempest tornado is kind of predictable and can be dodged with your The Hextech Ultimatum if timed correctly.

He's Tryndamere, just disengage when he ults with your Hookshot and you beat him. (don't get snowballed early in this lane, else you are doomed)

The main damage of Gragas is his full combo of Body Slam into charged up Drunken Rage and then instant Barrel Roll but if you can dodge his Body Slam in the first place by standing behind your minions and play around his long skill cooldown, he is just like a mage with a little bit of sustain and melee auto attacks (unless he is built as a tank, but that build would be better in the jungle)

Treat him like a Garen but you have to save Tactical Sweep to disengage, else he would collapse on you (must buy Executioner's Calling for this matchup)

you both have barriers and poke so you might not kill each other, but Jarvan Iv has a little advantage on this one because of the more frequent barrier from his Golden Aegis and long range poke from his Dragon Strike but he can't trap you in his Cataclysm because you can just Flash out or use your Hookshot to get out of the pit. 

his Granite Shield is kind of annoying sometimes and if he builds tank, you can't really kill him but he really can't kill you either if both players are of the same skill.

His way to beat you is to use Counter Strike on your second true damage proc of Precision Protocol if you can play around his third skill cooldown, you have a good chance of winning the duel.

You can't really kill him after level 5, but his skills is easily predictable, save your Hookshot to disengage when he uses Fling .

Just like Darius, you can't really win against him in long trade fights, but he is easy to poke with Tactical Sweep and Olaf mana run out quick in the early game if he keep throwing his axe, and he won't beat you before level 5 if you play your combos correctly and don't get hit by all of his Undertow (after 5, just play safe and don't Hookshot into him, he's still an Olaf and he is gonna use Ragnarok and run you down)

Like every other ranged matchup in baron lane, max your Hookshot and go for short trades with Hookshot + Precision Protocol combo >> disengage with Tactical Sweep You would still be traded back by their skills and auto attacks, so the best thing to do in this lane is to try to poke with Tactical Sweep , try not to get harassed by their auto attacks and wait for your jungler to gank you, so you can use your The Hextech Ultimatum to secure the kill with your jungler. 

If you are against a good Akali , this matchup is almost unwinnable. Normally, I would poke her with the Hookshot + Precision Protocol combo and disengage with Tactical Sweep . If you don't have any disengage when trading, she would most likely destroy you.

If she stuns you with her Riposte you lose, but if you can kick her and get the combo out you might win, don't walk up when her Duelist's Dance is in front of you, just walk away and wait for the vital spot from her Duelist's Dance to change to a better spot (everywhere except in front of you) or you can hug the wall at the side that her Duelist's Dance is at to make  Fiora harder to proc her passive and heal herself ( Executioner's Calling or Bramble Vest is recommended on this matchup)

Every ranged matchup is hard for Camille , but you can deal with him if you keep poking and find an opportunity to all-in him with your Hookshot and dodge a little bit of his Slicing Maelstrom damage with your The Hextech Ultimatum

Better Camille wins. 

Just don't get tricked by his Warrior Trickster or play around his Warrior Trickster cooldown and do your normal combo on the real one and you would most likely beat him, but if you got tricked just disengage with Tactical Sweep

if you misses your Hookshot , you are severely punished, but if you hit all your skills and don't use your second Precision Protocol proc when you are blind, you would most likely win the duel because he is quite squishy.

you can't win long trades with him no matter what you go, just poke with Tactical Sweep and if he pulls you (because his Apprehend and your Tactical Sweep are of almost the same range) just disengage with your Hookshot , and if he misses his Apprehend you can try to trade him with your combo and kite out with your Tactical Sweep when he almost reach 5 stacks on his Hemorrhage
