Luck & Gold Find from Affixes, Natures, Difficulty Level, Fortune Skill, and Green Shrines are all affected by their Caps.
Luck & Gold Find from Challenge Maps (including the Legend & Eternal Maps), Fortunate Perk, Luck & Gold Find 2 Hour Boosts, and Seven Deadly Sins Items are not counted towards the Caps.
My Farm Build has:
Epiphany (5)
+225% Crystal Luck & Gold Find
Fortune Skill 20
Nature Luck +25%
Nature Greed +25%
Item Drop +50%
Fortunate Perk +200% Luck & Gold Find and +5 Yard Pick Up
Enshrined Perk for improved Fortune and Quantity Shrine effects
on M3 this gives me:
+850% Luck
+850% Gold Find
+100% Item Drop
on Maps with the Green Fortune Shrine activated, my Luck & Gold Find are +1012.5%.
on Maps with the White Item Quantity Shrine activated, my Item Drop is +200%.
I average one of these Shrines about every three Maps, while I average getting both on the same Map about one out of every six Maps.
I don’t know if anyone else did something like this, but I think most if not all Players with a Farm Build have the Luck, Gold Find, and Item Drop maxed out. the reason I didn’t go that way is to have a little more attack and defense at the cost of a little less drops.
I also have Nadroji’s Chest & Head for double Nadroji’s Bonus for the +100% Magic & Rare Tier monster spawns and a little extra chance for the Enslaver spawns.
I also have one Eternalized Item (which I messed up and need to replace) for a better chance for Eternal Map drops. maybe I need to think about getting 2 of these, because I really want Eternal Maps to drop more often.
