WISH the odds were that good!
Odds of rolling the luck Property: 1-in-28. So the odds of any specific swing of a hammer giving you 160 Luck is 1-in-[(100 - Minimum possible Intensity of the Runic Hammer)*28/(Average number of properties per swing of the specific Hammer)].
So, the odds of making a 160 LuckBlade with each Runic Hammer are:
DC: 1-in-1,708 (1 Property per item, so around 37 DC Hammers)
Shadow: 1-in-752 (2 Properties per item, so around 17 Shadow Hammers)
Copper: 1-in-504 (2.5 Average Properties per item, so about 13 Copper Hammers)
Bronze: 1-in-420 (3 Properties per item, so 12 Bronze Hammers)
Gold: 1-in-320 (3.5 Average Properties per item, so around 11 Gold Hammers)
Agapite: 1-in-245 (4 Properties per item, so almost 10 Agapite Hammers)
Verite: 1-in-187 (4.5 Properties per item, so around 9 Verite Hammers)
Valorite: 1-in-84 (5 Properties per item, so around 5 or 6 Valorite Hammers)
A dev once said that the intensity range is not a linear equation (my experience says otherwise), but if it isn't, then the odds could be even worse. My equation also assumes 28 possible weapon properties and that the odds of receiving any property is the same.
