Vendor recipes

For more information, see Vendor recipe system.

A Gemcutter's Prism may be vendored with a level 20 support gem to produce a level 1 version of that support gem with 20% quality. Leveling gems in the alternative weapon set is generally considered a cost-efficient method of obtaining 20% quality support gems if the player does not have the means to obtain a large number of Gemcutter's Prisms.

Gemcutter's Prisms may be acquired from vendors by selling a single 20% quality gem, or multiple gems with a total quality of 40% or more.

Version history

Version	Changes
3.23.0	The vendor recipe for turning a Level 20 Gem into a 20% Quality Level 1 version of that Gem no longer works with Skill Gems, as the benefit Quality provides to damage dealing Skills is now more powerful. The vendor recipe can now only be used with non-Awakened Support Gems.
0.8.6	Added two new currency items with temporary art/names. They upgrade the quality on Flasks and Skill Gems respectively. (The latter was Gemcutter's Prism)
