mining and iron purity

[nosfirebird]

was wondering the purity ranges per level

also how important is the mining set to the purity of iron im on lvl 5 and only getting 0-4% but i dont get very far out from ladder range since im trying to rush to lvl 9 in 2 seperate mines

Well, the maximum i found on the first level was 17,5%. It was not far from the corner. 12-15% is usual somewhere in the middle of the first lvl( i mean, the middle between the ladder and the corner). For now i have 670 mining set. I think with the best mining set (about 750-800) you can get 19,9% on the first lvl, 29,9% on the second, 39,9% on the third etc. But may be, i'm wrong.
