Using Magma to Pierce Aquifers

(1/1)

Eagle_eye:
So that technique is fairly simple for breaching a single layer aquifer, but is it feasible to use it to go through a double aquifer layer, or should I stick to finding a vein of ore?

Urist Imiknorris:
Yes, magma can breach milti-layer aquifers. However, you need to take into account that the dimensions of the area you obsidianize will shrink every level.

Grumman:
Yep, it works. On the top aquifer layer, you need to dig out a (2*n + x) by (2*n +y) space, where n is the number of aquifer layers, and x and y are the maximum dimensions of the rooms cut through the aquifer. Each layer down you dig out a smaller area, like an upside-down pyramid.
