Sometimes you get to write things, and those things are ridiculous. For example, flow rate analysis of sprinkling holy water over 8 mile hexagons at a given volume per area unit. This is the most cheerfully ridiculous thing I produced for a book that is manifestly a pile of wild assertions.
If the divine ichor is worth some multiple of holy water, you can just generally shift your row on the chart.
Edit: I should say that I did a volume analysis with the classic basins from Gary's rules and the manufacturing capacity was such that it did not place on the chart. However amusing it would have been to compute how many thousands of basin/loads per hex/year were needed I did not choose to burden the table with (other, less game-useful) junk data.
Suffice it to say, the very best Gary-style basin is not going to help. Maybe you will keep them out of the vicarage if you work hard at it. #dreamsofruin #labyrinthlord #osr #ogl
