In the Krypt, there are four secret chests which are hidden. Each of the four areas contains one hidden chest and you'll be able to tell where the hidden chest is because of greenish-glowing bugs found near their locations (each one will be named "SEC #"). Each chest contains 5,000 Koins. You might have to wait around the area a few seconds before the chest will appear. 1) Deadlands - This is located near DL52. Go straight forward a little bit from DL52 and you should be able to notice the bugs. 2) Hollow of Infestation - Follow the wall from the lake where the area starts. It's in front of a demon head sculpture, along the wall. 3) Bloodmarsh - Go right from BM81 and it is along the wall, in front of a demon head sculpture. 4) Meadow of Despair - It's to the right of the entrance to Nekropolis, on top of slight mound.
