Start at cows until 30 or 40. Then camp rock crabs until you have reached the level you want. you could also just do soulwars, that works just as well.
I used iron knives.
Chickens till like 10. Monks till 20. Lvl 12 minotaurs till 40.
Meh prob not the best but thats how I did it on my mauler, would be better at rock crabs.
