what's the fastest way to earn construction experience? using butler (demon?) and getting planks through him or build kitchen right next to teleportation and bring planks by teleporting?

Using a butler is definitely the fastest :) I've always used the Demon butler but I've heard that the regular butler can be as equally effective.

have saw,hammer,100k depending on planks, noted oak planks thats 4 spaces

 

 

 

then 24 spaces for oak planks

 

 

 

once you are finished building use planks on butler to bring them back
