if u have at least 26 farming u can try growing limp flowers as they only take about 15 mins to grow and they give 3 limps per flower, that is how i get my limps although killing cockatrices is still the best way :lol:
let me add something, u could just stand in the middle and range them both. Can power range if u do not need ur arrows cause they spawn fast, in this case u do not need any food at all :lol: btw this is more then a tip
