Mob and Item Stacking

Mob Stacking

Almost all mobs will stack. The only ones that don't are Bee, Ender Dragon, Phantom, Villager, and Wither. We need this to preserve server performance, and it can also be used to your benefit.

Max stack size is 32.

Mobs will attempt to stack if there are at least 3 of the same type (unless other conditions are present) and if they are within a 5 block radius of each other.

Mobs wearing armor or holding something will stack with other mobs of the same type. When it merges with the stack, you may not see it as the top 'layer', but will eventually see it if you kill mobs (or peel off another way) in the stack.

A mob will not stack with another mob of the same type if:

• It's nametagged

• You already have one on a lead

• The mob is an active raider during a raid

• It is a different color (applies to Axolotl and Sheep)

• It is a different age

• It has a saddle on it

• It has horse armor on it

• It has a chest on it (applies to Donkey, Llama, and Mule)

Breeding

Stacking does not effect breeding. If you have 32 chickens in a stack and right-click with seeds, it will take 32 seeds from you (or as many as you have if you have less) and breed accordingly.

Babies will peel off when adult mobs breed.

Killing

In general, you cannot kill a whole stack at a time. The only damage that will propagate throughout all mobs in a stack is by magic damage (potions), and the only time the whole stack can die is by falling.

Unstacking

You can peel off certain mobs from a stack depending on if you can (and how) you can interact with them.

Ways to peel off a mob:

• Nametag it

• Dye the collar

• Tame it

• Shear it

• Babies will peel off if it has just been bred

Item Stacking

Items dropped on the ground will stack with nearby items of the same type and name, with a max stack size of 250,000 and a merge radius of 4 blocks.

If 2 items are the same but have different names, they will not stack.

I'm really sick of the word stack
