On the legendary item, more engravings seem to be available, possibly due to the fact that it already has a legendary engraving by default.
On the epic item (dagger) I could engrave 30% Armor Penetration in the past no problem but now I can't, seems there are more engravings than there is space available...
Hello again, apologies for the delay in getting back to you!
We have been discussing a similar behaviour with players and this appears to have occurred due to more than 100 engravings being collected, which results in the oldest engravings then being lost. Does that also sound like what you're experiencing?
Feedback has been forwarded to the ACOD team regarding this, however we are unable to guarantee if changes will be made, as the last patch has already been released.
Please let me know if you have any questions!
