Duration: 8 hours


Arcane Alarm is an abjuration spell that weaves a subtle yet potent magical warning system. This spell is not merely a deterrent but a vigilant guardian, a mystical sentinel that watches over a designated area. As the caster arranges the silver wire in a delicate pattern and gently rings the tiny bell, they create an invisible network of magical surveillance, a web of protection that alerts them to any intrusion.

Upon casting Arcane Alarm, you set an alarm against unwanted entry in an area no larger than a 20-foot cube. This spell can be set to protect a room, a corridor, a window, or any other defined space. The magic of the alarm is fine-tuned to the caster's specifications, capable of detecting the presence of creatures that enter the designated area.

You can choose whether the alarm is audible to all or only in your mind. An audible alarm rings out with the sound of a handbell, clear and resonant, alerting everyone within earshot of the intrusion. A mental alarm whispers a silent alert directly into your mind, ensuring that only you are aware of the breach.

The spell can be set to exclude certain creatures, either by general category (such as animals or your companions) or by specific individuals, preventing false alarms and ensuring that only unauthorized entries trigger the alert.

Arcane Alarm is a staple in magic shops, vaults, libraries, and other places where valuable or sensitive items are stored. It is also commonly used by adventurers to secure their campsite or protect their belongings. The spell offers peace of mind, allowing the caster to rest, study, or conduct business with the assurance that they will be alerted to any unwelcome visitors.

While Arcane Alarm is not a physically barring spell, its true strength lies in its ability to provide early warning, allowing for preparation and response to potential threats. It is a first line of defense, a magical sentry that stands watch while its caster attends to other matters.

In its casting, one finds a blend of caution and cunning, a magical expression of the age-old adage, "forewarned is forearmed." The spell weaves a layer of security into the fabric of the protected area, a silent, invisible guardian that ensures safety and tranquility.
