There's no answer we can give you really. It may take one person 20 tries, another 200 and another 2000. It's luck based so there's no "average" for that. :/
Took me less on some parts lol
Got 3x chan in like 5 tries? Luck.
If you really want to know the average, it's 342 (boots) + 224 (robe) + 185 (pants) = 751 tries. This makes for ~2600 damascenes if you count in the additional mats. Now, if you bought damascenes at 28 ec each, you would need ~73k ec. ON Average.On my mage I needed around 200 damascenes for top and pants, I still don't have boots however (after 500 or more attempts).
How did you calculate 342 tries on boots?I get 205 tries, my results are different from you.
