With this build you do very fast multiple crits above 1.000K dmg. Once you are at top attack speed, you are hitting multiple 1.000k dmg criticals per second. This of course depends on armor of the victim. On creeps I'm doing 1.100k dmg. You replace the Rageblade with a second Phantom Dancer at the end. I did deduct Rageblade and Builgewater dmg (70dmg) when calculating the critical hit damage. After recalculating the crit dmg. I think it's possible to do almost 1.4k dmg with this build. Let me know what kind of crits you guys are getting with this.

Even with the high critical hits my dodge is still 32% So I'm dodging and stunning as soon as the spell comes up. The cool down reduction is 12.77%. This is a large amount for early in the game when your leap strike has high cool downs.

At lvl 18 this means you can stun every 3.9 seconds. And you can leap strike/empower every 4.36 seconds. This allows you to almost chain your spells. By the time you use one, another one is up.

With the Hexblade, Exhaust, Flash and high run speed (+15%, +15%, +12%), almost no on can flee 1v1 or even 1v2.

Of course baron and dragon are easy solo if you are left alone. I've even gone a couple fights with finishing baron then killing the enemy hero.
