I did test today
I bought 10 map parts and did 10 runs today and here is my drop:
Total i spent 4,3 mil for map parts
Total got:
1,6 mil from selling shadow titanium armor
19 force core high (around 950K-1,3 mil)
16 upgrade core medium (around 4.3 mil)
19 extract potions (around 1.5 )
some materials for craft
and boots for Fuffster which cost 80 mil
so, if dont count boots i got about 9 mil
