WRT Yin / Yang swords:
We think their primary use lies in getting 2 free stackable death protections in small inventory slots, mainly useful for late-game bosshappenings. The damage has always been the extra. But I'll add this subdungeon to more regions when I playtest and investigate more carefully.
WRT Curses:
Yep, it's a DR cracker. And bloody difficult to avoid. And easy to lose control over. A dangerous debuff for resist/DR stackers.
WRT Martyr Wraps:
Also 10 gold cheaper. Though I suppose it was a bit cheeky to append another nerf when its value was already being questioned. We just felt the wraps had lost their thematic point somewhere. This idea was rather more rushed than some others, it'll probably change soon.
