Dreamer's Croc Scale Robe

[Royce]

As far as I know it is the best overall in the game for the mage. can't wait to equip it.

There are three pink level 35 robes in the Ancient Swamps. I actually prefer Mamboza's Croc Scale Robe because it has higher M/s, but I think most people would probably agree with you about the Dreamer's. Here are the stats for comparison:
Dreamer's: 38 Armor, 3 H/s, 2 M/s, 7 Int
Mamboza's: 38 Armor, 5 M/s

For me the tradeoff to get 3 more points of mana regen is worth it.
