Map invest is about 11Div ( Preservation Scarab ).
I roll the maps for 70+% pack size and 140+% Quant and atleast 90% more Scarabs.
Scarabs are 30-40% of the profit.
I get 6-9div out of Scarabs per map, so it's a gamble about 4-5 Divines invest for good Divination cards.
Maps i favoured for Curation Scarab:
Academy
Arsenal
Cemetery
DefiledCathedral
ForbiddenWoods
Foundry
FrozenCabins
Orchard
Phantasmagoria
Reef
Tower
VaalPyramid
