有關IRO的+9秋天頭 - 仙境傳說

功能描述如下：
A hairband with an array of autumn leaves attached to it.
It displays the beauty of an autumn forest for all to see.
When using the skill Wind Walk, SP consumption -20.
Increase long distance Physical attack by 5%.
If upgraded to +7 or higher, increases ATK by 2 for every 5 base INT
If upgraded to +9 or higher,, increases Arrow Storm damage
additionally by 2% for every its BaseLV 10 .

最近考慮強化遊俠的輸出，所以看到這個裝備
想問的是最後一句，每等級10增加箭雨風暴2%傷害

所以說Base175的話，就是17*2=34%的加傷嘍
不知道自己解讀有無錯誤，謝謝
