well i have 2 mob grinders in one world, from those, ive gotten a full set of iron equipment from a zombie grinder, and my skelly butt spawner has gotten me about 12 bows un enchanted and 8 enchanted all with power 1
So far, I got 3 iron shovels, 3 iron swords, 5 iron ingots, one helmet, one potato and 4 carrots from zombies. I also got 3 regular bows, and 3 enchanted ones from skeletons, and 2 gold ingots from zombie pigmen. I like to fight
3 music disks from creepers
two "power 1" bows
two iron ingots
a gold ingot from zombie pigman
since my world was an old one, I needed the carrots and potatoes for farming!
