Mounted mythical capes provide around 430,000 XP per hour while costing substantially less than mahogany methods. Reaching level 99 with this strategy costs roughly 100 million RuneScape gold and takes around 30 hours.

Mahogany Tables

At level 52, mahogany tables become the fastest commonly used Construction method. These tables provide up to 900,000 XP per hour, allowing players to reach level 99 in roughly 15 hours.

The downside is the price. Mahogany tables can cost over 200 million GP from start to finish. Efficient training requires precise timing with a demon butler and constant building and removing of furniture.

Oak Dungeon Doors

Players looking for a cheaper alternative can switch to oak dungeon doors at level 74. This method offers up to 550,000 XP per hour while using significantly cheaper oak planks.

Dungeon doors are built inside dungeon rooms and work best with a demon butler because each door consumes 10 planks at once.

Mahogany Benches

The fastest viable Construction method in OSRS is mahogany benches, sometimes called gnome benches. These can approach 1 million XP per hour when performed perfectly.

The strategy involves rapidly building one bench while simultaneously removing another beside it. Although incredibly fast, this method requires intense concentration and precise timing, making it difficult to OSRS GP sustain for long sessions.
