Minecraft – How does enchantment combining with an anvil work

minecraft-java-edition

I've been reading about how you can combine enchantments and put enchantments from books onto items. It seems like this could make for some very over powered things. Is there a limit to how many times an item can be combined/books used? Do enchantments stack? For example, if I have 2 pickaxes, an unbreaking II and unbreaking III would it become an unbreaking V? I've also read that some things cannot be applied at the same time, like fire and projectile resistance. Could someone go around and murder/steal from their foes, then go and steal their enchantments to make themselves more and more powerful? Is there a limit?

When combining enchantments, the enchantment caps out at a certain number. These are as follows:

Armor:

  • Protection IV
  • Fire Protection IV
  • Explosion/Blast Protection IV
  • Projectile Protection IV
  • Feather Falling IV
  • Respiration III
  • Aqua Affinity 1
  • Thorns III
  • Depth Strider III

Swords/Axes:

  • Sharpness V
  • Smite V
  • Bane of Arthropods V
  • Knockback II
  • Fire Aspect II
  • Looting III

Bow:

  • Power V
  • Punch II
  • Flame I
  • Infinity I

Rod:

  • Luck of the sea III
  • Lure III

Other/Most/All:

  • Unbreaking III
  • Efficiency V
  • Silk Touch I
  • Fortune III

Enchantments of the same level can be combined to get an enchantment 1 level higher; combining enchantments of different levels always yields an item with the higher of the two levels, giving no increase.

Trying to combine any enchantment that would give you past the numbers above will just give you the cap, EX: Unbreaking III and another Unbreaking III would only give you Unbreaking III, instead of Unbreaking IV

You cannot put Silk Touch and Fortune on the same tool, you cannot put more then 1 different type of Protection on the same piece of Armor, and you can not have any combination of Sharpness, Bane of Arthropods, or Smite on a weapon. All these enchantments are standalone and may override another if put on an item.
