Regarding the legendaries we already have a backlog of around 100 items. Most of them are already roughly game-designed and have a little backstory/legend (Thanks to “Trig” at this point!).
A lot of this stuff may change once we actually start polishing and creating these items, but its a good base.
The items themselves are (at the moment) divided in 3 levels of power so we have major and minor Items. The more powerful the harder to get.
Most of the items will provide unique active or passive skills which may have quite an impact on gameplay. So we will be careful to not shower the player with these items.
As a rule of thumb: If you get such an item, a few brothers have to give their life for that :)
