How much Accuracy do I need to hit Athena Pierce's Clone at a high rate?

I'm talking about:



Weapon attack: 260
Magic attack: 0
Weapon defense: 260
Magic defense: 220
Speed: 10
Accuracy: 210
Avoidability: 25

Also, how much time do I get to kill her?

 Spoiler

If you're gonna say any Bowman will be able to hit it, you're wrong cause I'm making a pure HP SE Mule and I had problems getting to 2nd Job even with Onyx apples and Amorian Baskets. ;x
But yea, at Lvl 70 the equipment will be much better (Lvl 64 bow, atk equips, etc.) so it shouldn't be that hard at all to beat her if I get enough time and got the acc. to hit her, lol.
