Cone of cold
From Ardrana
When cone of cold is cast, it causes a cone-shaped area of extreme cold, originating at the wizard's hand and extending outward in a conical shape. It drains heat and causes damage.
Note: This version of cone of cold originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
