A zombie pigman drops rotten flesh (earlier in the game, it used to drop cooked porkchop, it is now replaced by rotten flesh) or a gold nugget, ranging from 0 to 1 in the drop (sometimes, you might not even get a gold nugget). There are a few rare drops that the zombie pigman will drop, these include golden sword and random armor. It has a possibility of being enchanted as well. Fore more information on zombie piegman, read the official Minecraft wiki down below.
The drop rates for rare items on Timmy's drop tables vary, but generally range from 1 to 5.
Just like Wheat or Potatoes
I would say a skeleton spawner because they drop bows as there rare drop.
You can buy chainmail armour from villagers and you can also kill zombie with chainmail armour on them but its a rare drop so don't get excited thinking you will find one. You can also find chainmail armour in the creative inventory. With mods and TMI (Too Many Items) you can craft them the same way as other armors but with "Fire" instead. That's cheating, though. :)
abyssal whips are one of those items that you can only get as a drop; you cant make them. abyssal demons drop whips and if i remember correctly they are a rare drop.
Zombies are one of the first mobs, or mobile entities, in Minecraft. The zombie attacks you dealing damage depending on your difficulty setting and what armor you are wearing. Zombies also attack villagers and upon killing them, turn them into zombie villagers.(Zombie villagers can be healed when affected by weakness and fed a normal golden apple.) Zombies spawn in villages, dark areas, and when it is night. If an area is well lit a zombie cannot spawn unless its a siege in a village. The zombies will set on fire when exposed to daylight. On rare occasions zombies can pick up drop items and wield them as weapons or if it is armor or a head, as clothing. (Zombies do not set on fire by the sun if wearing head gear.) On normal difficulty or higher zombies can also break down wooden doors after repeated hits.
It's hard to answer this question, as the drop rates are not set in stone. Instead of being 'for ever 500 mushrooms, drop a claw', it's like a 0.5% chance. Nobody knows the exact drop rates but they are not EXTREMELY rare, meaning a couple of hours of training at zombie mushrooms should yield you a claw.
Well the rare drop rates are rare...
You can get Rare items alot of ways... i dont know what kind of rare items you mean but you can get rare items from monster drops, but you will need to be a member if you want anything REALLY rare. rg if you kill alot of steel dragons you might get some dragon platelegs/plateskirts or (i think the drop rate is 1-1001) a draconic visage. you can also buy rare items. if you save up your money and get a fair bit of it you could buy a pumpkin which was released in 2001 or a partyhat which cost alot.
it is very very rare
Rare items are expensive because people need to spend their rare items, too.
