what are the red yellow and blue squares when refining an item

They are for cash shop stones..

Red box - for Red Eyes - 100% ensures that your weapon won't break.

Yellow box - for Gold Miles - gives you extra success rate (this item is not out yet)

Blue box - for Blue Miles - 100% ensures that your weapon will not degrade.

^ EDIT ~ this item is NOT out yet :D

A little correction, it is only 100% if you get the perfect eye/mile.

Also while upgrading today I was thinking about the gold mile, wouldn't that completly ruin the economy is there was a perfect gold mile?

the 50% eye/mile doesnt exist anymore (they took it away a little while ago)... so u can only get 100% / perfects...

and i dont think there's a perfect gold mile... i think the gold miles comes in 15% or something like that

Ah, I suppose in my absence they removed the 50% without me noticing =P
