600+ Arrows Ice Rain Roa (3.15)

This is how i play this build
At the beginning of each map you can place some roa totem to generate inspiration charges. To generate more charges simply place more totem. Then you start running around and killing things. In case you meet many or difficult mobs you can place some or all totem for extra damage. You can also do a Vaal Roa if you want. When you run around your mirage archer totem will take care of the last survivors.
You can avoid the attacks with your dash/blink arrow.

For the boss you can replace your mirage archer for Cold Penetration.
In the boss fight you need to remember that you can often or always knocks back the boss. So when you place your Frost Bomb or Vaal Roa make sure the boss is in a position wher it can be hit. Preferably in a corner.
So the boss will be hit with your roa + 6 roa totems + 2 vaal roa
