1-9 Incarnam has a bunch of options piwis are pretty good till around 5 or so where you might try daredevil crabs they are pretty nice in Dofus.

9-20 Incarnam chafers probably wont hurt you with lvl 4 earth armor and they are great exp if you fall off incarnam after hitting level 16 mushds are great but be careful they agro and use water and earth attacks they can also take mp

20-30 Mushds are still good for a while though if u have lvl 5 wind armor you can probably take on piglets which if you dont mind the grind can actually take you to around 70. Fecas get a lot of solo options dinks, gobbals, crackrocks, treechnids (avoid fighting to many of them in 1 fight though as treecnassion unbewitches on critical hit)

30-40 Not much of a difference besides scaras which attack with neutral and whatever element they are (avoid fighting red scaras as they have 100% fire resistance) probably the only problem with fecas being able to solo so much is not knowing which thing they should kill cause there are so many options

40-60 Still not much of a difference cracklers are pretty decent and drop stones as well after 70 it gets a lot better

Note: You could buy the cheapest  dofus kamas . Just have a try!

60-70 no change

70+ With burning glyph its relatively easy to farm for resources you want like gob horns etc. If your good enough you can solo gobbal dungeon and can probably do small no level 80 kaniger mobs alone I recomend looking up something to kill from here on if you havent got an idea already.
