15 Hunting? Fastest Lvl up?

[Distad]

Should i do butterflys? Or keep doing cerulian birds till what level?

[DJ-Vimto]

this is what i would do...

Cerulean Twitch till lvl 19
tropical wagtails 19-23
wild kebbits 23-29 [kebbit claws being a usefull drop for crafting]
swamp lizards 29-31 or 29-33
spined larupia 31-33
barb tailed kebbits 33-37
*****ly kebbits 37-41 [take a chisel with you to fletch the spikes into bolts if you have the fletching lvl]
horned graak 41-43

i would go on, but i think that should be enough for now...

in all honesty that i mentioned above is exactly what i did when training hunter, and it didnt take too long either
