With this build you will be extremely OP in early game so take advantage of it.

Koshka is an early game hero. She will surely fall in late game. So try to take maximum number of kill till 10 min. After that it will impossible for her to play. So in late game u should try to support your carry. Be a second roam for your team.

Early game you are nightmare to almost all heroes. As Koshka is ability based use her B, attack, run. Repeat same. If you keep on standing besides your enemy you will die for sure. Don't use your A unless your enemy is fleeing. Make a combo use of first A and then immediately B. Don't initiate with your Ult if you are solo invading. Use Ult on low health fleeing enemies. If your opponent is hard carry like Ringo, Gwen, Saw who burst damage. During team fight use your Ult on such heroes so that your carry can finish them off.

Late game try to support your carry. Build Fountain Of Renewal for sure for your carry. Atlas Pauldron or Metal Jacket may depend on situation.

There are no such potential threats to Koshka as she is extremely op in early game and if you perfectly support your carry in late game your game is GG.

This build is extremely dangerous in early game, as all you buy is CP items. But you need to play it more carefully as you don't have any defence. Stay more on lane and try to gank enemy carry.

Aftershock should be your first item. You have to build your CP items as well as defence simultaneously. Your items order is as per the the situation. Keep Piercing Shard with you if you are not building Broken Myth first. Defence is your choice either support by Fountain Of Renewal and Atlas Pauldron or go for tight defence i.e. Aegis and Metal Jacket.

End your build with either Shatterglass or Frostburn. I will recommend Shatterglass as you need more damage. But there can be situations where you need to slow down your enemies. Don't go at all for Eve Of Harvest. As you cannot survive in late game for sure.

Lastly, this is my first guide, so please vote and let me know whether this build is effective or not for you guys....
