Every egg you find rolls its rarity 2 times and keeps the best result. Works on eggs from every monster, on every difficulty, for as long as you own it. • Does NOT change how often monsters drop eggs, it changes how good the eggs are. • Does NOT stack with other Egg Rarity passes. The highest one you own is the one that applies. • Applies to whoever lands the killing blow, so it works on your own kills. • Each difficulty caps how rare an egg can be. This pass rolls better within that cap, so it's worth the most on Hard and Nightmare.
