The Talisman was part of the inventory interface in the Blizzcon build (October 2008). It was seen between the two weapon slots in the [[inventory]], and when clicked a bronze, circular disk appeared over the character. There were 9 slots on the talisman, with lines connecting some of them. It had no function in the Blizzcon build, and could not be clicked or activated in any way.

In interviews at the show[http://www.diii.net/blog/comments/blizzcon-press-conference-with-jay-wilson/], Jay Wilson disclosed that it was something they were playing around with during development. It's called the "Talisman" and it's an "attribute modifier that used gems," according to Jay. There were no gems to be found in the Blizzcon demo, so no players could attempt to experiment with the Talisman, if it had even been enabled in that build.
