I am not sure if this is intentional or not but its lame. I was so hyped during the time i was farming 300 Tears to get this dagger. When i finally got it and transmuted to my level 80 dagger it didn’t glow at night while my friend’s original Ghastly Dagger still glows…..

Thanks for the reports! We’re working on a fix for this issue. 
For those who are curious about the cause, it appears that the bug is with the glow only being triggered if you’re in a map when it transitions from day to night, and won’t work if you go to a map where it’s already night.
