Currently, you can't enter into Entrana with any diary items that have combat stats. Whilst understandable for the Lost City quest and the content related to it, in the current days I don't really think that such a strict limit is necessary.
With the new farming update, a lot of people are most likely going to be farming, and since its really easy to incorporate other types of farming runs into a herb run I'd imagine a few others are probably going to end up having this experience too.
I understand not letting the wilderness sword in at all as it is quite literally a weapon, but an empty tirannwn quiver and the explorers ring realistically shouldn't oppose any of the beliefs of the Entrana monks. It'd be nice if the farming master cape is also allowed there for the free super compost, but it isn't as integral to herb runs as the aforementioned items are.
