eq:Foraging  

Here is the AA cost for foraging skill

1 = 3 AA
2 = 5 AA Level 96 required
3 = 7 AA
4 = 9 AA
5 = 12 AA
6 = 15 AA
7 = 18 AA
8 = 21 AA
9 = 24 AA
10 = 27 AA Level 105 required

I didnt keep track of the levels required except for level 2 and I didnt have enough AA (at first) for level 10, so I knew those for sure.
