How to get unholy hammer

[TaPhion]

Has anyone got the Unholy Hammer? I have one left, but I don't know how to get it. Is it right to get it from Yellow Node - Pyramid - The caretakers? I deliberately chose Navelea, and even though I chose the Navelea option, it didn't give me the Unholy Hammer. If anyone gets it, can you let me know?

Saw it in the shop after filling the lake with blood via rain of blood warrior card. Do not select the character option just tell the shop owner you filled the lake with blood. Holy rain and regular rain were also options but we haven't seen what they offer with those. Also uncertain if it sets the inventory or not. But we did indeed see the unholy hammer after filling with blood and telling the shop we did so.

Use the rain at the dry lake 2 nodes north of town.
