When selecting a stage for farming, it shows Bronze(nothing), Silver as +10% & Gold as +20%
likely equivalent; small= 10%, Med=20%, & large=30%
If you can use two drop leads of potentially (Rosa, Large x2), would that mean +60%?
but the question still remains, +60% more of what? Items and weapons.
if without drop assistance, you get 5 items, would that mean you get 3 more items (=5x0.6)
if the pool of item drops between Gear+Ingredients+Weapons is 105 different things, it must be a weighted wheel since 4* weapons are extremely rare.
weapons, 79 total -100%
