Casting humidify: Waterskin(0) to Waterskin(4)

Method guide

Use Humidify to completely fill empty waterskins. Equip a steam battlestaff to provide unlimited fire and water runes, leaving only astral runes and Waterskin(0) items to be withdrawn from the bank. Humidify fills each Waterskin(0) directly to Waterskin(4). With the steam battlestaff equipped and astral runes in the inventory, up to 27 waterskins can be processed per cast. Step 1: Withdraw 27 Waterskin(0) items from the bank and press ESC. Step 2: Cast Humidify. Step 3: Quickly press F1 to see when the waterskins have been completely filled. Step 4: Simultaneously press F2 and click the bank. Step 5: Deposit the Waterskin(4) items and withdraw another 27 Waterskin(0) items. Step 6: Repeat. Humidify gives 65 Magic experience per cast regardless of how many vessels are filled. At 800 casts per hour, 21,600 Waterskin(0) items can be converted into Waterskin(4) items, giving 52,000 Magic experience per hour.
