So this has a few of the stats and how much they will give if the gear is maxed out for them.  Also I have here the stats of all of my user created gear sets.

Max(Best stats from all parts added together):

2167 attack

6719 hp

44800 speed

351 turns/hour

177 xp/hour

1547 def

 

Elite Maze armor:

2100 attack

6512 hp

25854 speed

351 turns/hour

30 xp/hour

343 def

 

 

Garb of the fire mage(this was meant more for max hp and speed):

2007 attack

6719 HP

40120 Speed

7.85% accuracy

5.55% crit strike

4.15% block

Edit:  I decided to make a whole new set for this stat combination called the Garb of the Ice Mage:

2167 attack

6719 hp

177 xp/hour

260 turns/hour

3840 income/hour

Edit: how do people like these stats(keep in mind this is meant to be a raiding set):

2052 attack

6518 hp

27420 speed

4.67 crit

3.9 accuracy

351 turns

I'm pretty sure (about 95% sure xD) crit, block etc. are also used in raids, they just aren't displayed.

Some of the sets can be seen here also (I think maybe just ones with set bonus?) I think Aurum made it: List of Unofficial Sets

Nope, only Observer set had set bonus at the time of making the page, on the list, only your set has since gained a set bonus.

On somewhat related note: Interestingly, official sets, while recognized as a set ingame, don't give any set bonus.

I don't remember, I mean I don't think I asked for it out of blue, but I don't think CK gave it to my set out of blue either.
