I'm playing through Demon's Souls, but am running into issues finding the information I need for upgrading weapons. I currently have a Claymore +5. Is there a chart that tells me when I can start using dragon stones for fire damage? I'm making a faith build, but I more than likely won't utilize blessed-based weapons my first playthrough, because I'm trying to raise my END, VIT, and INT.
There are a lot of Dark Souls resources but I can't seem to find a chart or diagram that shows the upgrade path. Any help would be appreciated. Thanks!
