Shifters are an elemental node in the Runespan that allows players to draw nature runes from it. They are found on the middle and upper floors. It requires level 44 Runecrafting and gives experience in cycles of 86.8 experience each, though occasionally will also give 2 experience when a failed siphon is performed. Each nature rune gives 1.5 points.
Unlike creatures, players do not receive any rune essence when a node is depleted of its energy.
- A permanent but non-interactive version could be found on an experiment plinth on the first floor of the Wizard Tower along with similarly non-interactive versions of chaotic cloud, rock fragment, fireball, cyclone and nebula. Unlike the other nodes, this shifter looks very different compared to its natural version, being orange instead of green.
- Strangely, shifters are one of the only nodes (along with fleshy growths and vines) able to be seen on the mini-map, as a faint green dot. This is likely because they are 3D rendered objects as opposed to flat sprites like Nebula.
