Im having a hard time distinguishing between rare and unique items dropped by monsters. The difference between colours is very slim on my display. Is there any way of improving my situation?

Where can I get a lot of perfect gems for elixirs ?

Haha i have finally beaten destruction Baal after ~100 deaths with no SU's also quite a few more uberbosses.

another question
How can i get more magic find without sacrificing much momentum on K3K ?

Thanks
BTW do any merc make any difference in this build ?

Thanks a lot
Haha i have no real use of my A1 merc. She dies after the slightest mosters fart.

The guide recommends a crafted weapon with Mark of the wild buff as off weapon.
I recently looted a Shamanka staff with Bloodlust buff.
Which one would be better in my situation?

Im in act 5 just before Baal and i have already done mos of the easy ubers.

Thanks

Last time i played Median XL was almost 2 years ago.
Where can I find the full changelog since then? It seems to me that the game was vastly overhauled.
