Draven Q Spinning Axe:
BONUS PHYSICAL DAMAGE:
35 / 40 / 45 / 50 / 55 (+ 65 / 75 / 85 / 95 / 105% bonus AD)

This ability has an insane scaling with BONUS ad so BF sword is your best friend. You want items that give you lots of bonus ad to get the maximum damage from this ability. Draven is the best champion in the game in terms of scaling with RAW attack damage.

BT IE RFC is the best build path on draven, and LDR is a must. If you desperately need a survivability item before LDR then you can get it but you always want to build LDR after that.

In depth explanation for runes

CONQUEROR - This is the best rune for draven because it gives him AD every time he autos an enemy champion. So many noob dravens say that conqueror is bad because you never get the healing but thats not even the reason you take it. You take it because it can give you a lot of extra AD in extended fights. And since you lifesteal a lot with bloodthrister youll be in fights much longer to be able to stack conqueror to get massive damage from it. PTA is viable but its not as good as conqueror. With PTA you can burst down a single target but then you wont have a keystone for the next 6 seconds which is really bad.

TRIUMPH - This is the best for draven because you can survive longer in fights to get more stacks of conqueror. The gold is also noticeable on every takedown and it adds up. Its also an early game rune which suits dravens playstyle. Overheal doesnt come online until later and it doesnt make sense to go it on draven. Presence of mind doesnt give you the crucial extra health you need to stack conqueror even more and lifesteal back to full health. Only bad players take this rune on draven because they cant manage their mana properly and its more of a "band-aid" rune.

Alacrity - This rune gives you 3% attack speed at level 1 so it already gives you 75g worth of stats coming into lane which is really op because draven is focused on snowballing from the early game. If you take bloodline you start off with 0% lifesteal from it which is useless and wont get you that lead that you need as draven. Also your dps gets increased when you have alacrity while bloodline is more of a defensive rune that only gives you health stats.

Coup de grace - This rune is the best for securing kills as draven if you complain about getting KS'ed but you dont even have coup de grace then you should shut up. Cut down is useless early game and wont help you snowball like you want to. Last stand isnt worth because you should rarely getting low hp as draven if youre playing correctly.

Absolute focus - This rune synergizes with dravens Q scaling and youll almost always get the value from it since you have so much lifesteal and a shield protecting your hp bar from bloodthirster, that youll 90% of the game get the bonus AD from absolute focus. It can help you lots in farming faster and oneshotting enemies. If you go cleanse or exhaust, nimbus cloak is better since your cleanse and exhaust will now give you movement speed which can be valuable.

Gathering storm - This rune gives you insane value and scales infinitely. It gives you so much AD and draven is the best RAW ad scaling champion in the game.

10% attack speed - This is better than 9 adaptive because 10% attack speed is more valuable than 5.4 ad gold efficiency wise

DRAVEN TIPS UPDATED
Slow push is best method

You want control of the lane early so even if it means giving a ****ty leash to your jg you must get level 2 first

Deny enemy cs while building push (since u will have more minions can zone them off or poke with autos)

Poke the enemy when they go for a cs

If you hardpush fast enough you can reset the wave in the middle (your minions have to die to the enemy tower before the next enemy wave touches them)

If the wave resets you can cheese in bush

Vision wards are smurf, you can sit in river bush and put one down after shoving in a wave or when they think you recalled, and surprise gank them since they will want to shove

Play around your slowpushes and try to get enemies low so your jg can dive
Get the max efficiency of your autos

Think about the matchup and the jungler and decide how you want to play the lane and what you should be aware of

Manage your mana, conserve if under 50%

Dont use W more than once every 1.5s, because the movespeed lasts for 1.5 and the attack speed lasts for 3s

If you shoved before recall, the wave will bounce back to you and if you are strong enough, you can freeze

Freezing is the safest and most consistent way to snowball a lead on draven, you can only do this if you have control of the lane

If the enemies try to auto your creeps or break your freeze, you can easily run them down since the wave is at your tower

The enemy bot will try to roam mid if you freeze so spam ping your mid laner if they go mia

You can maintain a freeze but once youre strong enough you want to start pushing and getting plates so you can be on the map faster
Dont freeze if you need prio for drag/scuttle

Once the first tower is gone, clear the next incoming wave and swap to toplane
Keep up your tempo so that you can get all of the plates in top lane after bot lane

Once you swap to top call your jungler and support with you because they will probably 5 man top

Play around maximizing gold income inbetween objectives and recalling at an appropriate time to have better items for the objective fight

Tips for maximizing gold income: farm lane cs FIRST before farming any jungle camps because the camps will still be there after you finished farming the lane cs

Before you recall, always crash the wave into the tower

Be around the side of the map where the objective will spawn and call your top laner to splitpush on the opposite side since he has tp

Inhibitor is only worth it to get once baron spawns, so getting it before then is troll

In teamfights, focus on hitting your ult on as much people as possible and deal as much damage as possible, being efficient with your autos so you dont lose any dps
