As always, things get kicked off by the cheatsheet.

First of all, you got four builds. The Predator vanguard & Aftershock vanguard builds are alright, you explain those in the guide. However, you also got a Conqueror build that isn’t mentioned at all in the guide. You don’t even have notes that say something about it. Either add notes if it’s a very niche build or add it to the main guide.

Then you also have a “tank skarner for high elo” build. This one is getting a ?? from me since you do not talk about it at all and it lacks Trinity Force, the item you love so much on Skarner.

Your Aftershock skarner setup not only has a page with Sorcery secondary, but also has a page with Inspiration secondary and Precision secondary. These last two aren’t mentioned at all in your main guide. This should definitely be in the main part of your guide.

The items could benefit from some notes. Like, the Aftershock vanguard skarner has notes at Triforce/IBG but Predator vanguard skarner does not. The core of your Aftershock skarner build is pretty weird. I expected an IBG vs Triforce core like at Predator skarner, but you made a distinction between the jungle item enchantments instead?

• Smite: “Without Smite you lose the buffs from the other camps which is actually a huge loss”. What are you talking about here?

• Predator+sorc: “It allows you to apply lane pressure even while in your own jungle while it is on cooldown” First: shouldn’t the second ‘while’ be ‘when’? Second: what do you mean?
• Eyeball Collection: Why is Zombie Ward not an option here? You do get a sweeper and as a jungler you should be looking to clear out wards.
• Hunter runes: To me, Skarner seems to be pretty reliant on his ult, why don’t you mention Ultimate Hunter?
• Nimbus Cloak: Not mentioning the interaction between Nimbus Cloak and Smite is a crime imo.
• Shield Bash: This description is a bit of a ramble about health scalings. Refrain from mentioning Seismic Bastion’s max health scaling since it doesn’t really add anything (yes, shield gets larger = more damage = more synergy, but even without that, everyone gets the point).
• Conditioning: How dare you! This description is outdated! Conditioning kicks in at 12 mins, not 10.
• Unflinching: What is empowered bonus tenacity?

• Which skill do you skill at level 2?

• Dead Man's Plate: This description is a bit weird. Yes it is correct, but I’m surprised that you didn’t flat out mention the bonus movement speed (which is a very important stat on Skarner) and rambled about more ‘roaming’ potential instead (you’re not a laner...).

• General jungling: You mention that crimson raptor is not in range of the spire, however you have a video with a spire on the old location where it is in range of the spire…
• Aftershock route- standard route: You go from red buff to… krugs. But in your items section you say you gotta get Hunter's Machete when going the aftershock route and that you’ll only have to do krugs after lvl 3. This is just really confusing.
• You also mention the 30% reduced experience on first clear, however this was removed quite a while ago. I am suspicious that the clear sections are heavily outdated, but I cannot be sure of that since I do not play jungle myself.

• Herald: After all the in-depth gameplay talk I would like to see a mention of the value of the pre-14 minute herald. (e.g. using it when ~2-2.5 plates are left on a turret to get a lot of cash)
• Baron 1: Are you talking about their super minions or are you talking about your super minions? I am also really confused by the “how to avoid” parts here, what do you mean with ‘how to avoid super minions from pushing into their base’?.
• Baron 4: Dragon soul can definitely be worth a baron in some cases. Also forgot a ‘. ‘ before ‘No one is there to stop you’.
• Forcing a fight/baiting a fight: I would argue that forcing a fight is harder than baiting a fight. When baiting you sit in a bush and hope for them to facecheck. When forcing a fight you have to hope your team is coordinated enough to turn together. If half your team turns and the other half keeps fighting baron, you can easily throw the game.

Some spelling/stuff like that:

• Preface: ”While there are many different opinions on what runes and items Skarner should build, but I recommend this most general build for newer Skarner builds. ” Either delete ‘while’ or delete ‘but’. Also, what are ‘newer Skarner builds’? Do you mean players?
• Introduction: “He brings in powerful ganks with… and only gets stronger as the game goes in as he gets bulkier”
• Runes: “This keystone also allowed allows you to initiate fights with Impale without the need of Turbo Chemtank.”
• Runes: “ Celerity will also increase the movement speed bonus from Predator, Seismic Bastion… Missing a space between Predator, and Seismic Bastion.
• Runes Waterwalking: “You also get to enjoy the stats you get when contesting baron and dragon.” This sentence reads weird.
• Runes Waterwalking: “The bonus movement speed is also really great to get in more ganks from the river.” This sentence also reads weird. (Perhaps “The bonus movement speed helps a lot when ganking from the river”?)
• Nimbus Cloak: Congratulations! You received the single-sentence paragraph award! Seriously, you should split this sentence into smaller pieces.
• Aftershock+sorc: “This keystone also does damage after your resistances wear off, give both tankiness and damage all in one.” And “ Aftershock is also useful lategame as when you try to initiate a fight with Impale, the enemy team will through a massive wave of damage towards you,’’
• Items Boots of Swiftness: ’’This item is really niche and you'll almost never build it, but you may have to when they have an overabundance of consistent slows.” Who is ‘they’? and “The only time I ever had to build it was when the enemy team has had 2 Glacial Augments”
• Items Zeke's Convergence: “Build this item over Knight's Vow can dish out damage without much risk of being dived on by the enemy team.” I didn’t know a helmet could attack people.
• Ganking (Is it warded?): “Since Skarner cannot jump over walls, use blast cones to strategically unlock a gank parthpath you wouldn't be able to douse otherwise.” Also a kinda weird sentence.
• Objectives baron: “It's very easy to completely throw a game due to Baron that it’s bound to happen to you eventually,”. Although I understand the meaning of this sentence it reads kinda weird.

As for presentation wise: everything looks good. Jovy too pro at graphics, got nothing to say :(
