In Nolaria, there is a class of uncommon magic items called one-shot wands. As the name implies, the wand can only be used once and cannot be recharged. These wands are very similar to scrolls. The most common form is, in fact, a tightly rolled scroll, sealed with lacquer. One-shot wands can be used by any spell caster character class. They can be triggered with a simple verbal component ("Fire!") or by using the Trigger cantrip. Besides being less powerful that spell equivalents (Fire Ball, Lightning Bolt, Web, etc), they have an additional vulnerability. In combat, an opponent may attempt to use his (or her) Arcane Skills (if proficient). A DC-13 check is made. If successful, the one-shot wand is triggered in place.
