However, Caitlyn has way more range than Vayne. This can be effective, especially if you get the first shot off. Vayne wants to hit their opponent with 2 auto attacks, and then use her E "condemn" to knock her opponent away and also trigger a 3rd auto attack stack and her silver bolts passive granting extra damage. Consider a countered matchup such as Vayne versus Caitlyn. In the previous section I covered knowing your lane, which will help inform whether or not you can trade or would want to. This means there are more combinations of things that could occur and make it trickier to read whether or not you should go for a trade or what could happen if you do. In bot lane trading gets a little more complicated because it's 2v2. The goal is to make your opponent take more damage than you take in the trade. It's called trading because in most cases attacking your opponent leaves you open for them to attack you, and you're trading health and damage. Trading is when lane opponents attack each other in an attempt to 'trade' damage. This is obviously much easier when you've finished your support has finished their vision item such as Nomad's Eye. As mentioned before, keep control wards on hand, clear enemy wards to prepare for ganks, and try to make plays when you have strong vision. Be careful! However, a short river ward often isn’t enough vision to prevent your team from dying to a gank so don’t be lazy. The deeper the better, however how deep you can go depends heavily on your lane priority and confidence in the location of enemy champions. Vision: Refer to the image for some tips on where to ward. Don't do things like use an aoe ability on the minions as they come into the tower as it may leave many of them getting killed by the turret without your team being able to last hit. Pay attention to this to ensure higher cs farming. Similarly, it's usually 1 auto attack after 2 turret hits for a melee minion, but will vary depending on the exact stats and level of the minions. This means a support should hit a ranged minion once so that an adc or other carry can last hit the minion after the turret shot. For example, a turret shot will bring a ranged minion fairly low, but not low enough for 1 base auto attack to kill.
