Why would I want to use Worldclay?
The description of Worldclay says
Morphs into another artifact from your recipe. A recipe using Worldclay cannot unlock divine items.
As far as I can tell, unlocking divine items seems to be the main benefit of doing Beyond quests. So, why would I want to use Woldclay in a recipe if I can't unlock divine items?
Best Answer
Two kinds of loot are found on specific stages: paint and relics. Beyond mode can be used to try to get those specific loot drops by using the corresponding relics. With Worldclay, 3 stages of a specific type can be created using just one relic.
