Gathering
From Ymirheim Wiki
Gathering is a feature that allows the players to gather crafting materials, which can be used further for the crafting.
Once a material has been harvested, it disappears and respawns after some time (usually, 2~5 minutes).
The Gathering was firstly announced in the pre CBT2 progress report post.
The Ymirheim developers' comment regarding a newly implemented feature:
"Nothing very fancy yet, but it’s already something you can play with."
