Catching Swamp Toad for RS gold
This guide will make you somewhere around 500k RS gold in an hour and it requires no skill so this should be easy for you. Swamp Toad is a small creature with removable legs. If you choose to remove the legs, it will appear in you inventory. The legs itself can be use to make Gnome Cuisine and Agility Potions (mix with Toadflax).
In order to farm Swamp Toad, first go to the swamp north of Tree Gnome Stronghold which is almost right to the west of Grand Tree. You can also use the Spirit Tree to go to the Stronghold. It does not require you to pay RS gold so it’s a free ride.
Once you’re there, start picking up Swamp Toad as much as possible. A Beast of Burden is also recommended in order to have more space on inventory. Each Swamp Toad is worth 650+ RS gold. A full inventory can make you roughly over 18000 RS gold.
