While out of combat, Ashe's critical strike chance increases by 3/6/9/12/15/18% every 3 seconds, removed after next attack. Focus will now display a buff showing how much extra crit chance Ashe has.
This passive makes Ashe to a level 1 monster and if you have 100% crit chance plus volley, the enemy ad should be almost dead! Together with your support and some auto attacks it's an easy first blood if well played. You can invade with it, you can def your jungler with it and so on. It becomes a bit useless in lategame when you have crit items but it can be very strong and very annoying for the enemy ad if he walks into lane with one auto-hit bringing him down to half-hp. Try not to help your jungler with blue, let your support and mid do it, they'll understand if you explain it to them. You can help wolves if you want, your passive should be high enough when you come on your lane.
Q: Frost Shot
Toggle: Ashe's basic attacks slow her target's movement speed by 15 / 20 / 25 / 30 / 35% for 2 seconds.
Cost 8mana per attack
This is very cool because nearly no champ in the game can escape from an Ashe with Q on. You can kite(shoot, step backwards, shoot, step backwards...), chase or just put pressure on the enemies. If you got caught by an Ashe it's very hard to get away and if you got someone with your slow you can usually just finish him off with auto-attacks or your ultimate.
Ashe fires 7 arrows in a cone dealing attack damage + 40 / 50 / 60 / 70 / 80. Volley also applies Frost Shot.
Cooldown 20 / 16 / 12 / 8 / 4seconds
The earlygame damage is insane and the ability is just fun and one of the reasons why Ashe is so much fun to play. It applies frost shot and has like no cooldown by the end of the game. Ashe with blue buff can be terrible. More CDR and mana regen, means you dont have to turn frost shot off and you can spam Volley. Basically, it is a good damaging ability with a slow and it has a long range. Everything said.
Passive: Ashe gains 1 / 2 / 3 / 4 / 5 extra gold whenever she kills any unit.
Active: Ashe animates a Hawk to scout for her, revealing terrain as it flies toward target location.
People underestimate this, it can save the day. It's like Clairvoyance with the difference that this has a lower range but gives you gold. I get this one time lvl 4 and max it later.
R: Enchanted Crystal Arrow
Fires a large arrow in a straight line. If it hits an enemy champion, it will stun that champion for up to 3.5 seconds, based on the distance the arrow traveled, and deal 250 / 425 / 600 (+100% of ability power) magic damage. Additionally, surrounding units take half the damage and are slowed for 3 seconds.
Cooldown 100/90/80 seconds
Cost 150 mana
Probably one of the best initiating ults in the game, and one of the hardest to hit. Enchanted Crystal Arrow is the main reason why I play Ashe. Like I said in Pros & Cons, try to be as close as possible to your target, don't throw arrow over the whole map unless you know it will 100% hit. If youre in range you can Volley first and then arrow so the target can't dodge it that easy. Or if you have for example a Janna Support, let her hit Tornado first and then you ult. Just try to make it as easy as possible because if you miss Enchanted Crystal Arrow, the main engage is gone and you sometimes cant fight because of that.
