Could you please update the mastery tree?

This guide was epic ! First game with syndra i got 10/1 and second game 27/0, yes FLAWLESS !

Good item build, in depth guide. Thanks.
Should try and make it look a bit better by adding pictures and videos, ect.

Hi, I'd like to recommend some changes to your guide. First I wanted to say that overall you make some good recommendations for new players. However, there are a few areas I think could be improved upon.

First are your masteries. As a burst mage you definitely want to get 21 points into Offense, so I would suggest 21/0/9 as opposed to 17/0/13.

The other area are your recommended items. It's very risky to start with Doran's Ring first as you'll have no health potions or sustain if the enemy laner harasses you. Definitely start with boots and 3 potions first. I also would advise against Tear of the Goddess; Syndra is somewhat mana hungry, but blue buff and two Doran's Ring should suffice. If you're recommending Athene's Unholy Grail, why not pick up a Chalice of Harmony earlier if you're mana starved. Archangel's Staff is also not recommended, which follows Tear of the Goddess not being needed. Mejai's Soulstealer is a very risky item to build, especially for newcomers, as you need several stacks for the item to be cost effective. I would advise against building it.

My other small suggestion are your runes. Since Syndra is a very non-mobile champion, she benefits greatly from the additional movespeed Greater Quintessence of Movement Speed offer. I also recommend Greater Glyph of Magic Resist over Greater Glyph of Scaling Magic Resist for mid lane because Greater Glyph of Scaling Magic Resist only outscales Greater Glyph of Magic Resist at level 9. You want to have as much MR as possible for most mid lanes level 6 burst, which means Greater Glyph of Magic Resist gives the most resists.

You shouldn't worry having down votes. That just means that you need to improve something or revise it's content so that it'll turn out better than before~ :3

Nice guide so far ^_^ Obviously it needs a bit more depth but that'll come with time. All I will add is that late game it pays to stick close to another teammate, as she really is a glass cannon, and as such benefits from the support so no enemy gets to close to her. In fact I've found Morrigan a great partner for Syndra as she pretty much leaves you free to annihilate enemies thanks to her stun.

I really like your guide, though i would have some advice for you. switch the shoes to Ionian Boots of Lucidity (gives cooldown reduce) and
Mejai's Soulstealer to Lich Bane

Im not really bothered about the score, its more i dont want the "its a low score, must be ****" reaction xD cos personally i think my guide is pretty good. On Monday i will update it and make it even better, i would do it today/tomorrow but im moving into university tomorrow so i dont have time today :C

Oh, the community is absolutely ruthless :x

Don't care about down votes, and you can power through them and just make the best guide you can.

If you ever get down about the score of your guide, just remember, score really doesn't matter.

I get the feeling im gonna get down voted just because my build doesnt suit some people, hope the community isnt like that :/ im trying my hardest to try and appease people different people in terms of a build that is versatile :/

NEVER, NEVER NEVER NEVER use AP/Lvl quints.

NEVER.
