Over the weekend launched the new crafting feature for the modules and items found in Yixn's Trinkets crates.
This information is from the official post linked above.
There are currently six different Forge Sigils available for crafting.
Here are screenshots from the Golem Overlord Discord eye candy channel showing some of the possible results from using forge sigils for crafting modules.
It will be interesting to see what powerful modules the community is able to craft. Many players have already posted screenshots of crafting results, both good and bad. On the leaderboard, you can already see many of the top players have powerful modules equipped.
