you can die from self curses,also curse wethstone is bugged I couldn't use weapons after it,just used itself when clicking on weapon
I think it's only.. sort of a bug? Ran into the same thing but I was able to cancel it. Forgot how tho. The curse whetstone's activation goes into a kind of... chain usage. Whether that is intended or not, the best user experience would result in a single usage happening and returning the user to a state where nothing is being used/selected.
