In regards to leveling... how are weapons both rare and unique scaled?
Hypothetical: If a rare leveled weapon is found in Cave "x" and I start at location "y" in the beginning; at level 1, if I were ridiculously lucky enough to survive reaching cave "x" and get to the location and retrieve said Item; would its quality be dependent on my level, or will it be as powerful as it would if found at level 25?
5) Are loot and quest rewards level scaled, like in Oblivion? Will there be any powerful un-scaled items?
Bruce: We’re handling leveling stuff similar to how we did in Fallout 3, but with a few new twists that we hope players won’t even notice. The enemies and loot are based on the “encounter zone” you’re in, so it could be higher or lower level than your current level. We do have a new concept of epic or “special” loot that you can randomly find in many cases, regardless of the zone, and you will still get better stuff in the better zones with your level higher. Same goes for quest rewards. We try to make them appropriate for what you did. Sometimes that is random, sometimes that is a set item. There’s a lot of specific stuff that is very powerful, like the Daedric artifacts.
If you do a quest and your reward is supposed to be scaled, then it's not a scaled version of a particular item, it's a random item generated according to what is appropriate for the quest, your character, and the quest giver rewarding you with it.
If it's a specific item it's always that specific item. Daedric artifacts and the like are always the same, and you have a random chance of finding special high-quality loot anywhere in the game world.
