How does this review work:I'll be going into four 'main' topics: Cheatsheet, Content, Presentation and What can be Improved?. All of these topics alone can turn a great guide into an even better one. Just knowing the ins and outs of your champion alone won't be enough if you're not able to properly convey said information. The end goal is always to make it easier for the readers that come to your guide of course.I'll specify these main categories with purple text within this review, as well as some subcategories which will mostly depend on your guide chapters and for that I'll use the following rating system:

Cheatsheet

>Runes: Exquisite

>Summoner Spells: Exquisite

>Items: Adequate

I feel like instead of having it say "Mythic Option(s)", I'd change it to say "Mythic" for the 2 secondary builds you have that only makes use of one mythic, and "Mythics" for the main Engaging build that has 2 mythics. Provides a more concise space and gives the same purpose.

Along with this in your Guardian & Everfrost builds you have notes explaining the mythics, however you do not have any notes explaining your choices of the mythics in your Engage build. When shall the reader pick Evenshroud and when to pick Turbo Chemtank? Evenshroud seems to be the more recommended one (as it's your preview build for search listings) so it would be useful to explain why it'd be the more beneficial choice.

I'd change the title as well from "Final Item: Vigilant Wardstone" to just say "Final Item" for all the builds, title alone takes up more space than needed and it looks cleaner when it's less. Vigilant Wardstone still gets explained in the notes & by the title (as it's a final item) and so it provides the same purpose even if the title is more concise and doesn't mention the item by name.

If Rell prefers defensive stats over raw health most of the time and Warmog's Armor is one of the more expensive items she can purchase, why even buy it or consider it an option in the first place? Sounds like a pretty inconvenient item to recommend if there are better defensive options to choose from.

Personally I would move up Fimbulwinter altogether into the Engage build section and talk about it there. If the only reason you'd ever purchase it is due to Evenshroud, there's got to be a reason on why it's an important item. I have the same issue here as I do with warmogs. If the item is very inconsistent, has no defensive stats and heavily relies on tear stacking, then it doesn't sound like a very viable pick. However you mention that it's best against melee comps and long fights, so place it as an option into the Evenshroud build section & mention where the strengths of the item lies.

Gargoyle sounds useless from what the notes are explaining, should just remove it altogether if the item isn't a viable choice at all (especially if you're mentioning that it gets shutdown completely by a cheaper item, being Serpent's Fang). On that same note, you mention Serpent's Fang in these notes for Gargoyle, yet isn't seen anywhere in this cheatsheet?

If Abyssal Mask is a bad item to buy, don't include it as an option. No need to mention it if it's not a viable pick anyway.

I enjoy the explanations you have further down your guide about the final 3 items ( Silvermere Dawn / Redemption / Mikael's Blessing). However, you should at least mention something concise about them in your notes, rather than to point readers to the item section. Most people just want the quick information before e.g. a game, rather than the rest of the guide (and might come back to read the rest later on).

Would personally remove the last section for Niche items, since I believe some items can be removed and some items can just be moved to another build section where they would fit more. Up to you though.

>Ability Order: Adequate

Only thing needed to mention here is that you should place some notes explaining why W > E > Q max is the best option (it's the most popular option for her), but why? What makes it strong. Why are you even maxing W in the first place? What's the point behind it?

>Threats & Synergies: Exquisite

Don't feel like much more need to be said about this. From what I've read the descriptions for each matchup & synergy are great & concise and you include all the common ADCs + Supports as well as which ADCs have synergies with you and why they do. Very lovely.

Content

>Contents Table: Exquisite

Note: I would change the title for "Pro's and Con's" to just say "Pros and Cons", it just looks cleaner in my opinion for a section title.

>About Me: Exquisite

>About Rell: Exquisite

Note: I don't like lore very much, but the option is yours whether you want to keep it. The 2nd section on why to play Rell is much much better.

>Abilities: Adequate

Only thing I really have to say about this section is remove the descriptions that reiterate the ability description. I feel like these don't really provide anything useful to the readers rather than explaining the description of the ability that readers can just hover over the icon itself and/or check for themselves if they want to know damage numbers etc.

Instead I would rather have you talk about the purpose of the ability, much like you've already done with your Tips & Tricks, which is much more inviting. It's better to explain what strengths the ability has, why it's useful, who it's useful against, why it's a good ability and much more, rather than how much damage it deals. An example is the tip for the passive that mentions that it will steal your opponents armor & MR, this sentence is much better to have than going into detail on how much armor/MR you steal (also way easier to manage your ability section this way, since numbers for abilities on every champion changes everytime, tips & general explanations of the ability do not).

>Pros and Cons: Exquisite

Like mentioned before, just change the title in your Contents Table as well as the sidebar ToC to say "Pros and Cons" to fit with the title of your banner, and this section is already pretty perfect.

>Skill Sequence: Exquisite

>Summoners: Exquisite

Note: Need to mention how lovely this section is formatted.

>Runes: Exquisite

Note: Very well made altogether.

>Items: Adequate

Since Evenshroud & Turbo Chemtank is in its own section at the top for the cheatsheet, you should move chemtank to be above Locket. Then have your description for Locket and lastly Everfrost. Makes it more organized just like your cheatsheet.

You explain some good synergies and strenghts for Evenshroud & Locket of the Iron Solari, are there any good synergies, strengths or more things that can be said about Turbo Chemtank & Everfrost?

No mentions of Bulwark of the Mountain in this section, you talk about the first starter item part of it. Surely there is something you can explain about this item on why it'd be useful? Considering it's a pretty important support item to have.

Here you reiterate on how useful/good Gargoyle Stoneplate is, which is a contradiction to your cheatsheet saying it is not. If it's good, it should be in a build section as it's viable, right? If not, it shouldn't be talked about (maybe talk about Serpent's then since you mention that being better in your notes). As well as you talking about how good Warmog's Armor is, which also falls under the same category. If it's a good or useful item, have it in a build, if it isn't useful it more than likely was never a good item to have in the first place, no matter how niche it may be.

The icons for Watchful Wardstone and Winter's Approach should be switched to Fimbulwinter & Vigilant Wardstone (like you have in your cheatsheet) to keep the consistency. You can always talk about their lesser parts that you need to buy to get the final item in the descriptions of these 2.

Here you reiterate once more how terrible of an item Abyssal Mask is, and that you also dislike it. Which begs the question, why is it here?

>Example Builds: Exquisite

Nitpick #1: I would only remove the 1st paragraph of your Relic Shield description, it's the same as the one for the Item section and isn't needed, would just remove it and keep the 2nd disclaimer part. Or I would just remove that Relic shield paragraph, the icon and the title altogether and have just the text, it looks way cleaner that way IMO.

Nitpick #2: Like mentioned in your Item section, have the Turbo Chemtank build be above the Locket build, it is organized that way in your cheatsheet after all, better to keep the consistency going.

>Early Gameplay: Exquisite

Nitpick #3: Don't like the placeholder clip. If I were you, I would just remove them altogether (only keep the text there) up until you can find a good clip to use, then you can place it back. Pretty useless to show a clip if it's not the clip that is needed (Even if there is only 1 placeholder clip for this section).

>Mid-Late Gameplay: Exquisite

>Ability Usage: Exquisite

Nitpick #4: Remove the placeholder clips here along with the descriptions until you find the clips for the combos you need. If you still want to have such. It's just better overall. When you do find your examples and put them in, I would also change the title from "Click here for more information" to "Click here for examples", generally fits better for this section alone.

>Warding: Exquisite

Note: Title for the Mobalytics guide says "Jovy's Warding Guide" instead of "Mobalytics' Warding Guide".

>Matchups: Exquisite

Note: I feel like this section is already good enough and I do not need to mention more about it. You just need to add in more matchups and synergies, but you intend to do that anyway so.

>Conclusion: Exquisite

>Notes: Exquisite

Presentation

> Execution: Exquisite

Short Answer: Wonderful.

Long Answer: Beautiful presentation with graphics that complement the code colors very very well. The code is great and unique, does what it's supposed to do and it looks like the mobile formatting looks just fine!

>Theme of guide (color scheme): Exquisite

The color theme itself suits the chosen skin extremely well, there's not a lot more to say about it.

What can be Improved?

Apart from the few things I mentioned, the other things you can potentially improve on with your guide is to continue adding in more matchups and synergies to get a more broader perspective of the different champions that exist for botlane and the different 2v2 team combinations that you will both be with and against.

I would advice to at least make every single text version of the matchup/synergies. You can always put in the clips later on whenever you meet that matchup, at the moment I feel like doing this will aid you a lot even if the clips aren't there currently.

Overall Thoughts

This is definitely one of the cleaner looking guides I've got to see. I'm very impressed with how the code was done and that it works as intended. I hope this review is of help. :)
