Duel Between Masters

When fighting at Level 1, if Ezreal misses a single shot on Vayne, he's already lost.

A moment later, Vayne's 'Tumble' was ready again.

Another crossbow bolt flew out, and then Vayne immediately rolled forward, firing again!

This early in the game, neither champion had that much attack speed, so that there was more than a second between each attack. Vayne's 'Tumble' skill had the additional property of resetting her attack cooldown, which was especially crucial at this stage of the game, compounding the rate at which she dealt out damage.

Although his Mystic Shot had missed, Luocheng didn't panic. He was likewise keeping track of Vayne's skill cooldowns, and fired off a basic attack just before she used Tumble again.

Bamf! Flash!

Using Flash to interrupt his own attack animation, he withdrew beyond Vayne's attack range of 550 units!
