Welcome all, today I bring to you a guide for Quinn and Valor, Demacia's Wings. I hope you enjoy it, and would appreciate any constructive criticism you may have. I am open to changing the build, and have already done so a few times, so any items that u feel this build is missing out on, please dont hold onto them.

The combo that can get most damage output that I currently know of is to wait for valor to mark a champion with vulnerable. When this happens, make sure that you consume the mark, before opening with Blinding Assault. You then Vault into them, which causes another mark of vulnerable to appear. Against another ADC this is devastating, and can be a great harass early game.

Quinn is ranged ADC, who has good tools to help her do well.
After you get used to her abilities, you soon begin to realise the potential that can be utilised with all her abilities. It is important to know that I dont use my ult when team fights pop up, I use it for when I am getting chased, or when chasing an opponent. I have gotten many kills going into my ultimate when I respawn when I know a team mate is going to die, and pick up and easy kill as they recall or push lane. I use her E for many different uses, but her Q is how I initiate. I hit my Q before I use my E, knowing that counter attacks wont be as vicious as my attack, as the blind will stop them for a couple seconds. As Quinn you need to watch out for tanky champs who easily survive the onslaught. Recently Volibear and Sejuanni have been issues for me, as both have chase abilities and can soak my combo.

Pros

Blind
Utility tools
Scouting Map
Massive Move Speed Ult
Great passive for damage

Cons

Hard to Come back from a bad start
Falls fast when focused
High cooldown on W and R

I build boots and pots to begin the match. On the first time back I like to have Vampiric Scepter and if I do well Berserke Greaves. I then Build Bilgewater Cutlass, which goes into Blade of the Ruined king. Botrk has some ad, great amount of life steal and attack speed, as well as an active which makes a big difference in 1 v 1's. After that I build The Brutaliser, which is a great item on on many AD champs, as the CDR and Armor Pen go a long way in disassembling opponents quickly. Around this time I will get the enchantment Alacrity for my boots, which speeds Quinn up that extra bit when her ult is on cooldown. This counters one of her weaaknesses, which is how she gets caught a lot. Next I get Infinity Edge, for more damage and crits.I get Frozen Mallet for its passive, which is great in chasing and escaping situations, as when I play Quinn I usually use Vault to get away from attackers. I get a bloodthirster at the end, although if your dying to quickly then I would get Guardian Angel or Warmog's Armor.

I choose to Max vault first as it is a great utility ability. Once used to its effects, it can be used for pokes, kills and getting away. Also blinding assault has a solid affect, but is solid enough with one point at the start of the game. Heightened Senses is a great ability, but has a huge cooldown even when maxed. It is great after a team fight to mop up enemies who are low.

If you have a poor start, you need to farm more, and assure that you have back up when going in. Do not buy an enchantment for your boots just yet, and focus on the AD aspects to items, Like the B.F sword when getting Infinity Edge. Remember that you have a lot of life steal already, so The Bloodthirster is pointless when doing bad. You should farm up creeps until you have more AD, then when you go into fights the enemy will expect you to do terrible. Quinn is focused a lot, so make sure that when you zero in on a target, to kill then quickly get behind your tank or support.

When doing well, it is fun to build more utility items such as Statik Shiv, just because you do a lot more damage than the enemy. In most encounters you should be wreaking havoc. But be warned, because of how well your doing you will be focused heavily. It is smart to build some of the more tanky items earlier, and maybe getting a guardian angel. This means that when they focus you, your other team mates can still do hefty damage to them, while you can withstand more. Be sure to not be cocky, but do not hold back on them.

In Summary, Quinn and Valor are great champions who have a quality kit for getting kills. I hope you've enjoyed my build, if you did, give it an up vote, and if you give it a down vote I would appreciate a reason, so that I can change it appropriatly.
