rare arcane cantrip cold conjuration 

Cast [>]

Range 30 feet; Targets 1 object

Your gelid shard drinks down nearby heat in a futile attempt to sate itself and achieve a level of frigid cold unheard of on the Material Plane. This allows you to cool a drink, make a hot pot safe to handle, or other, similar minor effects. Once cooled, the object's temperature is subject to its environment as usual. You can also solidify ambient moisture into a solid object; this temporary object is of negligible Bulk, made of non-magical ice. The object looks crude and artificial and is extremely fragile—it can't be used as a tool, weapon, or spell component. Once created, it melts as normal for ice for the ambient conditions.

Heightened (3rd) You can create simple objects of ice with up to 1 Bulk and of a level not exceeding 1. Such objects must be rigid. You can only have one such object created at a time; if you create another, the previous object melts instantly.

Heightened (5th) Items you create can be up to 4 Bulk and 4th level.

Heightened (7th) Items you create can be up to 8 Bulk and 8th level.

Heightened (9th) Items you create can be up to 20 Bulk and 12th level.
