Druid solo'ing at lvl 30 - weird gap

[Gumbo]

You have to remember that Mammoths in Everfrost are split up in different areas. You have the easier Mammoths in the front of the zone and then you have the harder Mammoths more toward the back.

I would say the split between the Mammoths is the old Shaman temple with the Shaman who sells spells. Go pass him and cross the first ice covered river and these Mammoths are tougher.

Also have to remember that level 30 is the first hell level and it can be a pain if soloing.
