2.) How much lp do you get per log?
3.) What have you found to be the most efficient method of grinding em, in terms of dream catcher lay out, how you collect dreams quickly, do you use em on the spot or store them in a cupboard, etc etc.
4.) Is this the fastest way of grinding lp aside from high tier hunting? If not, what would you recommend?
I haven't played in 8 months and just got full change/peaceful for max lp gain so I'm trying to figure out the best thing to do. Thanks for the help.

Here is what mine looks like. I have harvest bound to 3 and I use the palisade sign post to store logs so they're quick and easy to grab.
