Hey, before giving you advice it would be good to know a bit more about your playstyle.
First of all are u dragon or light mage and are you using a buff? Imo best thing to improve as a mage is equipping your buff and hitting with both chars, like this I did pretty good even compared to warriors.
Looking at your gear I would try to get myself:
1. 60 helmet+6 / bonus doesn`t matter that much and depends on what you want to do, but I wouldn`t advice to change much, better improving other things
2. phoenix shoes+6 with some hp and crit / blockin hits is just too good imo and you can still use your boots for your buff
3. try getting a better pearl neck or use this one on your buff getting a clean +9 for your main + a htn with some crit+hp
4. I would try changing bonus on your bracelet
Just my opinion though I don`t know your exact plans, for example if you plan making demon tower on your own it might not be worth to change the brace.
Next to those points I would always look out for bamboo bells on market with 35avg+.
Wish you good luck with your adventure I started with 2 mage`s on Odyssey too and never regretted it unfortunately I don`t have much time to play.
