I have recently noticed that I need mob drops and I do not wish to pay for them I need designs that are good on EMC. Rates with caves lit, etc... This is literally the only design I know of... Please share ideas, or maybe screenshots of your own designs you created? Thanks!
Try this: https://www.youtube.com/watch?v=37WuZBE6BPU I built this over an ocean and didn't need any lighting up. Works very well.
If you want an enraged mob farm, use any technique, filter the mobs into a lava stream. The normal ones die, the enraged ones survive. Then make them take some damage and kill them as you would in an EXP mob farm.
