Ok so I started fighting the star marmots outside the town, then moved on to the funguar thingys near camp brentbranch. I did this to about lvl 4
Next i moved to the north east of central forest and killed whatever i could handle (fungaurs, marmots, etc) up to lvl 8ish.
Then i went to camp emerald moss and -slowly- killed Thistletail Marmots. I've been doing that since and i'm level 13 now (and by level i mean marauder rank 13 not phys lvl)
The best camp i find is near the zone to the east.
1-4: path to + around camp brentbranch
4-8: Northeast central forest
8-13: Camp Emerald Moss
Anyone know where to go after this? or any suggestions?
