Ritual 1
Cast 1 day; Cost precious metals, rare incense, and herbs worth a total value of 15 gp per spell level
Primary Check Arcana (expert) or Occultism (expert)
Targets 1 object
Duration unlimited
You place a tiny elemental wisp within a single object, usually a mirror, statue, or other mundane-looking item, to serve as an alarm. Shattering or otherwise destroying the object frees the wisp and ends the ritual's effect even if the object is magically restored.
Critical Success The elemental wisps inhabits the object and willingly serves you to the best of its ability. The wisp becomes aware of the target object's surroundings and can telepathically contact you with a range of 500 feet. It reports to you about intruders or other changes to the room in which it's located. You must tell the wisp what the criteria for the reports will be—for instance, when anyone not openly wearing a certain symbol enters the room or when an item is removed. The wisp has a +5 Perception modifier and observes the room using normal vision, normal hearing, and touch.Success As critical success, but the range of the telepathy is 100 feet and the wisp's Perception modifier is +3.Failure You're unable to harness the spirit. The ritual fails.Critical Failure The elemental wisp is trapped in the object as with a success, but it refuses or is somehow unable to help you. The elemental might have extremely low Intelligence or simply be spiteful. Regardless, the object's reports are always misleading.Heightened (4th) The range of the telepathic link increases, allowing the wisp to contact you anywhere on the same planet. Its Perception modifier increases to +10, or +12 on a critical success.
Heightened (6th) As 4th level, except the wisp can see invisibility, and its Perception modifier increases to +15, or +17 on a critical success.

Range 10 feet; Targets 1 ley line or ley line node up to double this ritual's level
You draw upon surrounding magical energy to empower a ley line, enhancing both its positive and negative effects.
The duration of an empowered ley line's benefits increases: when you successfully Tap a Ley Line that's empowered, you gain its benefits until the end of your next turn on a success (1 minute on a critical success)
You take double the damage if you fail to Tap a Ley Line that's empowered and double the damage from the ley line's backlash effects (if any). If a backlash effect has a duration, that duration increases: a backlash effect that would ordinarily last until the end of your next turn now lasts for 1 minute, effects that last for 1 minute now last for 10 minutes, effects that last for 10 minutes now last for 1 hour, and effects that last for 1 hour now last for 1 day.
Critical Success You empower the ley line until the next turning of the season.Success You empower the ley line for 1 week.Failure You fail to empower the ley line.Critical Failure All casters take damage and suffer the ley line's backlash as if they had critically failed to Tap the Ley Line. This damage and backlash is enhanced as if the ley line were successfully empowered, leading to increased damage and longer backlash effects.Secrets of Magic, page 216.
