Hello! A few Questions about mp washing

1. How much MP do i need as an archer if i want, 20khp?
2. Since im mp washing (putting ap into mp) do i need to wash it out before i do 4th job adv? Or can i wait til 135 to wash all the ap out of mp?

Thank you!

 

Oh and also I have 3k hp , so really I only need 17k Hp. How much mp would I need for 17k hp?

 

You can wash it out whenever for a BM. I also suggest that you stop at 18750, there is no benefit for going all the way to 20k and you would be at 30k with HB at 18750 ^^
