Jhanifer's deliquescence

Jhanifer's deliquescence was a transmutation spell that functioned exactly like transmute rock to mud, except that it transformed ice into cold water (approximately 40 °F or 4 °C). If the water was dispelled or affected by cold magic, it regained its icy form and refroze in a natural manner, depending on the surrounding temperature and conditions.

This spell was developed by Anastra Syluné Silverhand, the "Witch of Shadowdale", while she traveled under the assumed name of "Jhanifer".
