Hey...just looking for tips on how to "brew" or transform the nerbs we find in potions.

When you mouse over an herb it says "SHIFT+LMB/RMB to interact" (spelling?)...what is that?
Do we need something other than herbs to brew something and how to brew?!?!!?

Thanks!?!??!!?!
!?!?!?!!?

You will later find equipment to make potions. That Shift-thing is that you can split stacked items.

Thanks a bunch!
