The required environment for catching these consists of a blue vine blossom, a lergberry bush, a thermal vent, and an orange tree. As with other plant requirements in Herblore Habitat, the correct combination will take effect as soon as it is planted/built. It is not necessary to wait for it to grow. Igneous jadinkos can also be found climbing down jade roots inside the Jadinko Lair, placing resources on the offering stone. These jadinkos cannot be hunted.
