Farming wood in the black woods. Portal needed!
Step 1 – Troll
Find a Black Woods biome, get a workbench and portal ready to build. Look for a Troll with tree club.
Build workbench and portal to you home base.
Step 2 – Kiting
Kite the Troll around and make it hit the trees while dodging his hits.
Easier with a friend so you can switch and deposit the wood while other teammate is kiting the Troll.
Step 3 – Profit
Collect the wood (grab the Megingjord for more weight) and teleport back to your base when full. You should be full in 2 min or so, depending how many trees around.
