I wrote an post 2013. I just checked back at it very fast, and at a glance I saw that this idea did also (many of my ideas ended up) in D3.
The post: https://www.diablofans.com/forums/diablo-forums/diablo-iii-general-discussion/78584-talisman-transmute-enkeria-edition
So It seems like the Talisman was the idea, and from it the devs changed it to be part of the horadric cube (or whatever it is called these days in D3), and the shard system.
The images is also gone, because I was stupid enough using photobucket at the time. Today I mostly use Imgur, and there seems to be no guarantee that images will last for that long, so pro tip: If you are linking images, link them from own paid website! lol.
Okey. So if you guys read my old post (long one, as usual) what are your thoughts about it? Could we use charms in it this time around to make cool stuff, get cool effects etc?
I imagined a grid, similar to what Minecraft did when it was fairly "new", you but materials (charms) in a specific order to get something out of it. 3x3 grid or bigger.
Now, what this would give you is
1, cluttered inventory with charms you can't use until its time. Fix: Have a bag that charms can be in, infinite number, the bag is only opened and available when you are fiddling with the talisman.
2, do we even need this in D4? It seems like runes will make some, items with do others and you got skills and traits this time around. What more is there else to give us in terms of customization and buffs? Hmm.
