Call me a nerd, but realize that Aftershock deals 15% of your opponent's maximum health as extra damage. If you have a good finger skill you can unload all four of your Glimmershots on your opponent. 4 Glimmershots times 15=60% of your opponent's max health with your next basic attack. Great build (although I use a slightly differing one).

Love the build! Kestrel is. MY far my favorite hero at the moment. But the cp side that she has is amazing! Her skill show procs any on hit effect! You build is good, but only for damage. She's a stealth her like taka, but with less health and defence it seems. My build for Kestrel right now is Shatterglass, Broken Myth, and alternating current. No you may ask why alternating currtent, but if you read her skill shot, it reloads basic on attack speed. And if you don't know already her energy consumption/ management is terrible. I often find myself buying energy batterie first if I lane or crystal bit in the jungle. The alternating current and broken myth you already know is a great combo, and when you run out of skill shot arrows with kestrel and they have a sliver left, without alternating current it's almost impossible to get away. I also go boots clockwork and 1 defence because she's so squishy. The clockwork help manage you energy and drops your snipe to a 25 sec cd. I'm hitting 800 - 1000 damage on fools who don't buy shield vs me lol. Practically health bars.buy every other shot doing that extra damage is insain, combing it with your stealth is amazing! I would suggest trying out alternating current instead of aftershock, it's pretty powerful.

I signed up just to upvote your guide man! Its a really good build and personally I like cp Kestral than wp because in this B is really usefull with the extra enhancements.
Anyway good job on your first guide man you made me like Kestral even more now, nicely done.

even from only using her in solo practice mode, I noticed how powerful she is, and this build is something I'm going to try for sure, since I like the clockwork (I find this to be a must) and the aftershock would be a fantastic addition for sustain.

will definitely try this build.
