Are the Reckoning demo items functional? Can I actually use/wear them in-game, or are they only ornamental?
Yes, the items you unlock via the Reckoning demo are all things your Reckoning characters can equip and use. Each item does have stats and lore associated with it, but they are not intended to be the best equipment you can get.
Will the Reckoning demo items be available to all the characters I create in Reckoning, or only the first character I create?
The demo items you’ve earned will be available for every character you create in Reckoning.
Do any of the Reckoning demo items have a level restriction?
Some of the Reckoning demo items do have minor level and attribute equip requirements, however they are intended to be great beginning equipment and are leveled appropriately for that purpose. All your characters will either already meet the necessary equip requirements, or be within one level of doing so by the time you reach Gorhart, where the items are located.
Do any of the Reckoning demo items scale with my character’s level?
No, the Reckoning demo items are intended to be awesome items to help you get started in Reckoning. They’ll give you a great edge as you forge your path in Amalur, but they do not level up with your character.
