Золотая руда

Dream cherries are dropped by Dreamwood Leaves. Those leaves generate on Dreamwood trees all throughout Alfheim. Eating a dream cherry will give you a big saturation boost, which means it takes much longer before your hunger goes down again.

Elementium Ore can be found underground roughly on the same levels as iron in the overworld. In Alfheim, where the magic is much more present than in the overworld, the raw materials are naturally generated. There's no need to infuse them with mana.
