I’ve built the delving bench, put 50 eldarium in and tried to delve hardened steel daggers, perfected hardened steel daggers, and star metal daggers. None of them will go. All are at 100% durability. The star metal and plain hardened steel ones are freshly crafted.
I’m not willing to sacrifice legendary daggers to see if they might delve.
I tried moving the bench to another location, and dismantling and rebuilding it, but it made no difference.
Not sure if all delving is broken since I have very little eldarium as yet and daggers are my priority.
I have images but since I’m a new user it won’t let me upload them but they just show the bench with the eldarium and daggers in the delve section not going anywhere.
