Marble vine

Marble vines can be obtained in Herblore Habitat. The marble vine is dropped by igneous jadinkos (blue vine blossom, a lergberry bush, a thermal vent, and an orange tree are needed to lure them), which requires 74 Hunter to trap. Marble vines are the secondary ingredient for the juju farming potion.

In Geology, marble is formed by the process of metamorphism, and not by igneous processes, despite being dropped by igneous jadinkos.
