Go to forgoten Temple get out of there at 33lvl then move to ant nest till 39 lvl.I Suggest you get a better armor,some jewels and lots of antidotes you will need for both spots.
TIP:When you enter temple move from left side and try focus at Roxide lvl32 he got 2 servants got very good xp and you are gonna need some bandage cause it cast bleed.
