Hello,

Please elaborate on why do you think that Root of Warrior doesn't work correctly, by just stating this we cannot assist you.

And Indra has a double cast in a single round if you have the chakra but if you don't use the 2nd time it will not be taken over to have 3 mysteries in the next round.
As for the Cooldown, he has a 2-round cooldown naturally the only way to reduce this is by using Wind Main (Dance of Impetus) or using another ninja that can reset his cooldown.

I see, well please go to our Discord to the CS or Strategy Channel as there will be multiple people ready to help you faster than for you to wait for someone on Forum to reply to you.
