One word: Enchanting.
Systems are ready for testing, we just need the areas in. At least, I would urge any in depth evaluation to wait until after we've experimented with that.
Interesting. I look forward to learning more in time.
What I don't like is certain named items with a story and two or more people have that item. The example comes to mind is the //cant spell but know it starts with a C [insert name] holy great sword that the woman supposedly impaled herself on. That should be a one of a kind item, like something like the sunsword.
However, there should be more than one Tempus Rebuttals because they are replicas of a particular blade. Not saying you cant have a holy great sword, just that they should be more replicas not the main blade.
Hence I think that there will be more imitation magical weapons like the Tempus Rebuttal and very few named ones.
And with a good DM event and an a lot of blood, sweat, and tears, you should be able to find or make a item of legacy.
Which requires
Research, Research, and more Research
Building up funds to support expeditions
Building up resources for expeditions
Gathering regular members of expeditions
Going through hell on Expeditions
Making it out with item or more research to make item
Then having a story to go with item that is partly your character's story.
So, if you want a flame tongue you must research it. Either seek what you have to do to make it or find out where it is hidden. Go look for it with some friends, and seek it out and hope you don't get killed.
Well that is my take on enchanting or acquiring decent magical items.
