Hidden revival herb in ch2 xen base

[TeneSicarius]

I don't know how many know this, I haven't seen it on any of the walkthroughs that usually talk about hidden items, but there's a revival herb in the Xen base in the volcano. In the top right room, bottom left corner, on a cushion. What makes this really weird is that this area is limited-time, and you don't have the itemfinder yet, so you'd have to manually check all the tiles to find it. I don't know if there's anything else like this. It's been there for a few versions now; I've found it in v12 and v13.
