what's the approx. price for a craft attempt when choosing the "luck" path with proc? and how much does it cost for the 'safe' path ?
It depends on server prices for mats, but I'd guess it's roughly...
Luck: Prototype Greatsword = 250k, 212 Drenium = 400k, 212 charcoal + 100 acid = 500k, 6 Expert Vendor Fluxes = 600k, Pure Drenium Ore = 250k, Pure Maigcal Aether = 250k.
1.35mill fixed price from vendor, 2.25 million per combine.
Safe: Prototype Greatsword = 320k, 1040 Drenium = 2mill, 1040 charcoal + 242 acid = 2.5mill, 6 Brilliant Vendor Fluxes = 3mill, Brilliant Drenium Ore and Brilliant Magical Aether = (Honestly I don't remember what these are selling for, but I'm gonna go ahead and say they're 5x more expensive than Pure for simplicity) Ore = 1.25mill Aether = 1.25mill
5.8mill fixed price from vendor, 10.3 million per combine.
Again this is only a rough estimate and could vary greatly depending on server prices of mats.
