Boots of Swiftness
UNIQUE Passive: Enhanced Movement 3.
With any other boots you would be too slow. And you are in need of speed
The Black Cleaver
30 Attack Speed, 55 Attack Damage. Passive: Physical attacks reduce your target's Armor by 15 for 5 seconds, (maximum 3 stacks).
The item has exactly what you need. Attack speed, attack damage and armour penetration.
20 Attack Speed. UNIQUE Aura: Gives nearby allies Champions 20% lifesteal, 20% Attack Speed, and 30 Health per 5 seconds regenerated. Reduces the Armor of nearby enemy champions by 20.
This item is great because it gives you an essential amount of attack speed combined with The Black Cleaver so you dont need to buy Phantom Dancer. And since you are carry in the game it gives lifesteal,attack speed and health reg. to nearby allies.
30 attack speed, 30 attack dammage, 30 ability power, 15 critical strike chance, 250 health, 250 mana, 12 movement speed. UNIQUE Passive: 25% chance on hit to slow the target by 35% for 2.5 seconds;on cast, increases your base attack damage by 150% for one attack
Personally i think all should have Trinity Force, no duscusions there, besides it increases your amount of mana
75 Attack Damage, 20 Critical Strike Chance. UNIQUE Passive: Critical Hits now deal 250% instead of 200%.
The damage this item gives is way to big to miss out on Ashe. Its a must to have this item.
60 attacke damage, 25 life steal. Passive: Gain an additional 1 Physical damage and 0.25 lifesteal per kill. Maximum of +40 damage and 10% lifesteal. Bonuses are lost upon death.
I would personally go with this you can also go with Last whisperer for extra armour penetration
