I almost use this exact build every match as well except I get eve of harvest as well because without the battery, I'm always out of energy.

I am gonna join I'm sending an invite right now

CP Koshka is way more squishier than tank Koshka, but can work if you have a good tank. Keep in mind though that you're going down fast if your tank is gone

Not a fan of a tanky Koshka... CP all the way

I would say build a fountain instead of ageis in low crystal cases and THEN add tension bow.

Could you add Tension Bow at the end to get the extra attack, or is that space better for consumables?

I tried it (I was skeptical) and realized yep, you're right! An ally had to come in late, and this build kept me alive! Thanks for the build!
I had to ise flares through the game, but I only needed 4 items. It was great!

Oh, just for saying, this build is not mine. It's hardek's. I'm just sharing it for other people. Also, journey boots are built last. I just did travel boots so people don't build it as their first/second t3 item

Mythmakr, this is the most effective way to play koshka. This is the way the meta has shifted, Koshka is extremely effective with this build because she only needs the after shock to do massive damage, and she can still support the team with crucibles. The journey boots are unimportant and always the last thing to buy. Alt current is also not necessary. Hardek from Nemesis (who many call the best koshka in the world) uses this build. Its just too effective.

Why stop with travelboots? Journey Boots better compliment your passive. Also, Alternating Current can keep her head above water- Especially when bought right after using infusions.
