I upvoted, It is a nice guide, could have more BBCoding but what you have is good as a start, I think that you put a great amount of effort into this guide and the information is viable, your item choices and explanations are pretty good and so are the explanations for runes and masteries. That being said you could add more content in like a match-ups section but that is optional, I would however advise you to take some time to go more in depth and add a gameplay sector instead of a tips sector but I believe that has already been mentioned. Just keep at it and add a bit more content in some places and flesh out the summoner spell choices a bit more, tell the reader why ghost and exhaust are viable spells tell the reader how to set up a kill at level 2, tell the reader how to lane as Sion as he generally has a hard time early. I think in time this will be a really good guide as it seems you are already putting the effort into writing it.

ok, yeah, ill try that, thanks man :3

To correctly spell Doran's Blade you need the apostrophe. Very minimal BBCoding, check my signature for a useful guide on coding. The entire items chapter is a wall of text, you need some coding to make it visually appealing, so people will want to read it. Break it up into smaller sections, Like Core items, Situationals, etc.
Put pros/cons at the very start of the guide. Tell them why Sion is a viable champion, and why they should play him. Don't hav a tips chapter, have a gameplay chapter. Talk about laning, jungling, and whatnot with sion. Tell them how to play him, not suggest some tips.

haha, thanks guys ^.^
i'll use your tips.

For the getting masteries picture there are multiple resources on MobaFire but I think the coding for that and runes are just [runes(or masteries)=1]

Definitely read the guide I linked up there, that's my main tip^
Well, that and a spellchecker. Hehe.

Any other suggestions?

I dont think i saved it when i added in boots xD. thanks ill give it a look over.

Bud, that guide that lildrummerdrew gave will help you so much :)

It takes time to make good guides though :)

You should really add boots though, like @lildrummerdrew said.

yeah im a bit sketchy on guide coding, i dont even know how to get a picture of masteries in xD. that will most likely be my next goal. and nashors is appart of a full AP build, sions natural damage even when building AP makes still makes his ultimate usefull, nashor's is a good way to build AP and still make your ultimate useful. in my opinion. but i will change the guide if others reckon a different item would suit him instead.

I would completely take out Nashor's. Just me. Maybe add some lifesteal options, and umm, read the guide on how to code guides, I haven't used much of it yet but it's REALLY useful.

Yeah, i can undersatnd, im not the most competant writer out of the bunch. but it ry my best. i have fixed the boots, thank you for that obvious mistake. also the AOE damage that comes with sunfire cape is quite handy with farming, added with the AOE from Ravenous Hydra. and if you could tell me what you mean by my end paragraph is bad. (guide is still under contruction.)
