What's your chanter spell line up and hotkeys/buttons

[Kawhi]

I'm not all that far on my chanter alt (lvl 24), but so far I'm not feeling a huge benefit from tash. I still cast it almost every pet that I charm, but it feels to me that my charm isn't lasting that much longer because of tash.

That being said, it never resists and costs little mana so it's a very efficient MR debuff, so it doesn't have to help that often in order to be worth it.

Do you start feeling the benefits more as you get higher?
