Normally alert gives 1 coin from first boss and 2 coins from last boss. Thats without having 2 platinum augments reach rank 17. Today, I defeated 1st boss with 2 platinum augments (both above rank 17) and only got 1 splintered coin. There is no issue on Poseidon's coin drop; 2 normal +2 bonus coins.
Isn't that how it's supposed to work? I can't remember if it says extra coin per boss or per instance but could of swore per instance
I checked the drops again and I think I misread the loot tab rows during a raid run. It seemd like I got 4+2 marks from grail so thought same will occur for alert too. So the intended way is bonus marks drops from last boss of all wonderverse instances then this thread is a "false alarm" "Not a Bug"
