I've gotten a new status lately, "The Haunt". Card text reads:

[cost: 1]
"Gain %s Gold"
"Become more haunted."
"Ethereal, Exhaust."

I can't seem to identify exactly what mod it comes from. It's a rare status that you really can only obtain as a random card from a card-reshuffler. I've searched through various mod source codes but can't find it.

Because it's not actually in your deck but randomly gets added to it at the start of a fight, I don't get the blurb that tells me what mod it's from. What mod is it from?

Context: This card increases by +5 gold each time. That's stupidly overpowered. (Especially with golden armour, gaining thousands of max hp each turn is funny).
