I think that the new Journey Boots are great on Taka. The most fun I've ever had on him was in Battle Royal, full build (Shatterglass, After Shock, Clock Work, Aegis, Frostburn), and boots on a 12 second cooldown. They just cannot stick to you, because you hit, disappear, and by the time they realize that they're out of health, you're in a bush waiting for cooldowns. The new passive it grants you (resets boot cooldown to 12 seconds if you auto attack an enemy hero) is really fun to work with.

Wasn't that "munions following an invisible taka" thing a bug? I'm pretty sure they patched it up.

This is amazing!!!

3rd point in X-Retsu can only be gotten at level 12

If petal has already targeted you with her munions, Petal's munions can follow you even when you are in Kaku, making her quite dangerous against Taka because it basically stops him from sneaking away from the fight.

Glaive has one of the highest health in the game. This cushions Taka's burst damage, allowing Glaive to return damage onto Taka. Most Glaives would be built WP, so against a fountain as your only defense, it should be easy for Glaive to take Taka down. (Assuming Glaive builds some shielding to complement his health)
