The Humidify spell will fill all empty water-carrying vessels in a player's inventory with a single casting, including buckets, fishbowls, jugs, vials, watering cans, waterskins, bowls and clay. A player receives 65 experience regardless of the number of vessels they have filled. Fishbowls and watering cans are not tradeable if they contain water.
Players travelling in the desert may find this spell useful so they can refill their waterskins without cutting cacti. Farmers on Lunar spells also find Humidify useful when farming multiple allotments, and may use Cure Plant and Fertile Soil hand in hand.
Casting humidify can also be a good way of training magic while making a fair profit. This can be done by buying empty vials from an NPC store such as the Shilo Village General Store or the Lunar Isle General Store and converting them into vial of water. You can also use humidify to help save time when making soft clay by having the dry clay in your inventory, and casting the spell. This turns all clay into soft clay. Players should use a staff that provides unlimited Fire and Water runes (such as a Steam battlestaff) for maximum efficiency.
These tables assume all items are bought on the Grand Exchange and sold afterwards for guide price. All staves may use equivalents (eg. Mindspike (water) instead of Staff of water). A large rune pouch in the ammunition slot may be used to store runes for additional inventory space.
This table shows the difference of the price between filled and empty vessels. After subtracting the cost of the cast, that would be your profit.
