How to create a 23% Quality Gem - Path of Exile

For most gems, the max quality is 20%. There are, however, ways to increase the quality of a gem beyond 20%.

1. Vaal Orb corruption

Like most items, gems can be corrupted using a Vaal Orb Vaal Orb. Corruption on gems can potentially lift the level or quality percentage of a gem above the maximum of 20. Corruption can also convert a gem into its Vaal skill equivalent, if one exists.

The chances are the following:

  • No effect (other than adding the corrupted property).
  • Add or subtract one level. Max level gems can exceed their normal maximum this way. A corrupted gem at the normal maximum will not continue to gain experience.
  • Add or subtract 1-20 quality. Gems can have up to 23% quality this way.
  • Change the gem to its corresponding Vaal Gem.

In order to make the best profit, craft a level 20 of 20% quality gem is the best choice.

In theory, the chance of a 23% quality gem is 12.5% assuming no weighting. 25% for each possibility: nothing, Vaal, quality, level. And then, it’s 50% for going up or down (when having rolled quality or level). But it’s still heavy RNG.

2. Beastcrafting recipe

Beastcrafting is a method of crafting by sacrificing beasts to the blood altar in the Menagerie. Each beastcrafing recipe requires four beasts to be sacrificed, with most of them requiring one specific Red Beast and three Rare Beasts. The four chosen beasts are released into the arena surrounding the blood altar and must be killed to complete the recipe. If the player dies during the attempt, the recipe fails and the beasts are lost.

The table below displays the resulting crafts when sacrificing to the blood altar.
