"Other little tweaks emerge. You can carry three weapons instead of two, with one of the demo’s character builds carrying a Halberd for big damage, an axe (temple knight) for speed and a catalyst for sorceries. You can dual wield weapons now, and shields too."
The temple knight, which was undoubtedly presumed a faith class, uses sorceries. Perhaps they recreated the magic system? I'm glad that the axe weapons are speed weapons now as well, which will allow for some cool combos. And I don't know why it would be effective, but you can dual wield shields...
