[Variant] Absolute Zero - D&D5e (Patreon)

Potion, rare

___

Brewed from the chilling essence extracted from the breath pouch of a White Dragon and infused with a drop of its icy blood, this crystal-clear elixir holds the bleakness of winter within its depths. Stored in an enchanted glass globe that’s impermeable to any force but deliberate breakage, the potion holds an all-consuming cold ready to be released.

To activate its power, one must break the glass globe, exposing the potion to air. Doing so releases an omnipotent winter breath that spans a 60-foot radius centered around the broken globe, engulfing the surroundings in a sudden arctic environment for 1 hour. Every drop of exposed liquid freezes instantly, the ground within the area becomes difficult terrain.

All creatures in the area when this effect happen must succeed on a DC 15 Constitution saving throw or take 3d8 Cold Damage and becoming Restrained by jagged formations of ice until it or another creature within reach of it uses an action to break away the ice. Those who succeed in the Constution saving throw muster enough strength to resist the worst effects of the cold, taking only half the damage and avoiding the icy restraints.
