Hello, i am ian (partyian in game).
I play on the eu west server.
I main mostly support champs as i feel more comfortable playing supp.
Ashe is one of the few champs i feel comfortable playing with outside of my supp champ pool.

I have played league in early season one.
I stopped playing league after a few months because my old laptop suddenly couldn't handle league anymore.

In early season 5 i started playing the game again.
Before i became lvl 30 i always played Ashe and i still play her a lot.

I am silver 5, but that's because i stopped playing ranked after i got sick of all the flaming of almost every person i encountered there.
I hope to get out of silver in season 6 and i hope i can end somewhere in higher elo, so i can even learn more about the game ^^.

Infinity Edge
I always build infinity edge as a first item.
The extra critical damage it gives works great on ashe as she can easily keep hitting enemies while she slows them or stuns them with her ult.

Phantom Dancer
I see most people using statik shiv on her, but i just feel like i lack something when i play ashe with statik shiv.
Of Course it is useful in teamfights and also for wave clear, but i don't feel like it gives ashe too much of an advantage as phantom dancer.
Phantom dancer gives more atk speed + the same amount of critical strike, but the reason why i choose phantom dancer over statik is because of the passives.
With the passive of phantom dancer i get more movement speed when i'm 500 units near an enemy champion, what makes me able to chase them better while slowing them.
And then the second passive makes them deal 12% less damage for 10 sec if they decide to retaliate, which gives an even bigger advantage if they are able to deal more damage in a shorter amount of time normally.

Berserker's Greaves (Enchantment Alacrity)
To be honest, i just prefer this boots enchantment over others.
Enchantment furor would give a better advantage while chasing others, but in lane and in teamfights i feel like i have more mobility when i use alacrity.

Bloodthirster
When you get further in the game you obviously need lifesteal as an adc in order to sustain fights.
If you don't need to build a defensive lifesteal item like Mercurial Scimitar i recommend just building a bloodthirster as it gives you 75 attack damage and 20% life steal.
The passive shield is also very nice, if you are able to hit an enemy champion in a teamfight while staying behind your tanks you can keep absorbing damage while not taking any.
I often charge the shield with jungle camps before i engage in a teamfight so i sustain even longer.

Lord Dominik's Regards
If you get too far in the game you will need armor penetration as tanks will probably already have bought armor items like: thornmail, dead man's plate and frozen heart.
The item gives 40 attack damage.
The first passive gives up to 15% bonus damage (1.5% per 50 health difference).
So you will deal a lot more damage to tanks.
The second passive let's physical damage ignore 40% of the target's bonus armor.
Combine that with good runes and masteries and you will deal tons of damage to tanks that will have a hard time getting to you because of your slows.

Runaan's Hurricane
Runaan's Hurricane is the reason why i pick phantom dancer in early game over statik shyv.
It gives 40% attack speed, 30% critical strike chance and 5% movement speed.
So eventually i will get my movement speed, a lot of attack speed and 80% total critical strike chance.
The first passive deals 15 damage extra on every hit, but the second passive is the reason why i pick runaan's.
The second passive makes 2 bolts hit enemy champions in a 375 range of me dealing 25% of my attack damage to them.
In team fights that is very useful.
For example: If you can't get to the squishy damage dealing opponents, you can hit on the tanks with a chance that you hit the squishy ones.
Especially in late game team fights that is useful as you might just deal enough damage to the second and third opponent you hit to kill them or to make an ally survive.
Well, that's my perspective and i know it won't always work out like that, but it has helped me in a lot of situations using this build.
