Bismuth Prism is found randomly from Iridescent Ore gathering spots in the Lava Caverns (not “iridescent Crystal”).

There are three Iridescent Ore nodes in the upper part and two nodes in the underground part. These are all fairly easy to find, although navigating the Lava Caverns in general can be somewhat tricky.

(1 of 5) 1. On a ledge between the broken bridge in-between areas 2, 3, 6 and 9. South of Sub-Camp 2.

1: On a ledge between the broken bridge in-between areas 2, 3, 6 and 9. South of Sub-Camp 2. If you’re worried about falling, you can walk down to it from the north side.

2: Towards the north of Area 6, at the far end of the jutting out area, across the narrow bridge.

3: Atop a pillar in the underground part between areas 6 and 8. If you gathered from the previous ore node, fall down to Area 6 and climb up to the sides.

4: Towards the north of Area 10, above a hole in the ground. Right near Sub-Camp 1. If you don’t have the sub-camp unlocked, head over to Area 9 and use a great wirebug to reach Area 10. If you gathered from the previous node, you can fast-travel to climb back up or use the gust of wind directly south from that node.

5: North-east corner of Area 13, which is underground. From the previous node, fall down the nearby hole. Go through Area 14 towards the north entrance of Area 13. Then drop down to the left, where there’s low ground.
