Magic Items

Wand, rare (requires attunement)

This wand has been transformed into an alien, glassy green crystal that’s cold to the touch and morphs its appearance slightly overnight. When within 5 feet of a portal to the Far Realm, the wand glows a sickly green and writhes like a snake.
This wand has 7 charges. While holding it, you can use an action to expend some of its charges to cast one of the following spells from it (spell save DC 15, +5 to hit with spell attacks): ice storm (4 charges), ray of frost (no charges, or 1 charge to cast as it as a 5th-level character), or sleet storm (3 charges).
The wand regains 1d6 + 1 expended charges daily at dawn. If you expend the wand’s last charge, roll a d20. On a 20, the wand melts away, forever destroyed.

Wondrous item, uncommon

While wearing these dark lenses, you have Darkvision out to a range of 60 feet. If you already have Darkvision, wearing the goggles increases its range by 60 feet.
These googles’ lenses are made from a strange, green glass and are always cold, even in the hottest climates. Due to this chill, a character wearing the googles always feels as if the temperature is near freezing, unless the actual temperature is even colder.

Wondrous item, common

This 3-inch cube of solid brimstone generates enough dry heat to keep the temperature within 15 feet of it at 95 degrees Fahrenheit (35 degrees Celsius).

Wondrous item, uncommon (requires attunement)
