Some inspiration for people which we're struggling with Arch Tempered Kushala Daora
Very unlucky it could escape from me!

Tactic:

1. Plant bombs before pull
2. Use Rocksteady
3. Aim on the Head with Wyvern ammo 2 Times and Kushala should fall down (in most cases Kushala will Roar 2 Times in a Row after the pull so the first Fall of Kushala is for free!)
4. Change to Cluster 3
5. Shoot with Cluster 2 Times if your lucky u can use a 3rd Shoot without reloading (If you don't have a Proc shoot 1 Time with Cluster 2 and then start immediately reloading and crafting new ammo)
6. Reload Wyvern and Cluster Ammo and Crafting New Cluster 1/3 and Wyvern Ammo
7. Restart from Step 3
8. When Kushala is low HP use sleep ammo 2 so it wont escape and give one cluster shot immediately after it
9. Craft Ammo, Craft new Mega Barrel Bomb -> Plant bomb -> Reload Cluster / Wyvern
10. Wyvern Ammo Pull shoot some Cluster and you're done

Other Notes: When Kushala starts flying with the Tornado u can stand close and Shoot on the Head with the Wyvern Ammo
And its possible to Run out of Ammo if you're unlucky with the Xenojiva set bonus procs
