Withdraw 27 clay, cast Humidify once, bank, repeat. Soft clay demand comes from Construction and Crafting trainers; the clay/soft clay spread is small but the volume is high.

Requirements

Skills: 68 Magic
Quests: Lunar Diplomacy
Note: Lunar spellbook. One cast converts a whole inventory of 27 clay; rate is bank-trip limited. Steam staff reduces rune cost (not modelled).
