This article has a money making guide here: Humidifying clay.
Please add tips to the subpage, rather than the article below.

The humidify spell will fill all empty water-carrying vessels in a player's inventory with a single cast including: buckets, fishbowls, jugs, vials, watering cans, unwatered saplings, waterskins, bowls, and clay. Somewhat surprisingly, it does not work on Empty cups. It yields 65 experience per cast regardless of the number of vessels filled. It can also be used to extinguish the wall of flames in the Chambers of Xeric when fighting Great Olm or to refill waterskins in the Kharidian Desert instead of needing to cut cacti.

A steam battlestaff, or staff of water and tome of fire or vice versa can be used for maximum efficiency. It can be used to train Magic while making profit from some of the items above:

Input Output Profit

Jug.png Jug Jug of water.png Jug of water 22

Waterskin(0).png Waterskin(0) Waterskin(4).png Waterskin(4) 26

To maximise experience per hour with this spell, put a fishbowl underneath the spell (similar to High Level Alchemy) and to the "F1" and "F6" keys (or custom F-keys) to switch between spellbook and inventory. Left-click empties the fishbowl. Casting High Level Alchemy is always cheaper when alchemising profitable items while this method always results in loss. Upon hearing the sound effect, all vessels have been filled.
