Construction
How to train Construction on BLST: a player house with rooms and furniture, with planks and a sawmill close by at home.
Construction builds your house. Rooms give you useful things like a portal room, a pool, or an altar.
Where to train
The estate agent, demon butler and sawmill operator all stand at home, so you do not need to travel. Build hotspots in your house with planks, and let a butler fetch more. Rates are multiplied by your XP rate.
