Hi guys, please help me answer these questions if u can

-In DD, if u reload u can get different stats of an item? Is it the same in D2?
-I like the way we have a topic "Listing of all info, tutorial, spoiler" in DD, but I can't find the same one in here. Does it exist? If not, could anyone please kindly give me the link where I can see all things like list of items (weapons, armor, etc.) available in game, skills showcase?
I'd like to see the appearance of items and skills but I can't find them anywhere, even the wiki seems to miss lots of info.
-I'm thinking about making an Assassin in D2 because that class was really weak in DD. Is it possible to make an assassin with some keys like: dual daggers (I prefer claws or iron gloves-boxing more but I guess those types of weapon are not available in this game); invisible skill (Embrace Shadow); high dodge-accuracy and critical rate; very fast attack speed?
-In DD, the best armor set is Dragon set, however in D2 after searching I found many types of Dragon sets, so I'm confused how they look like and which one is the strongest. Also I don't know the best weapon in game too (I hope D2 is not like DD when focusing on SWORD too much!

) So it'd be nice if someone can please kindly list me those items, then I will have more effort to find them in game.
-Finally, does the difficulty effect anything like drop rate or stats of items (like more difficult = better chance to drop good items, or items have higher stats)? Because the game sets difficulty = Hard by default, I'm confused if I should set it to Easy or Normal first and increase later like in DD
Thank u very much!
