Targets up to 20 formless spawn of Tsathoggua
Saving Throw none; Spell Resistance no
This ritual alerts formless spawn of Tsathoggua to the caster’s location and interest in communication.
Usually, casters use them as surrogates for contact with Tsathoggua itself. The formless spawn gain no special ability to contact or travel to the caster. One or more formless spawn will generally move to encounter the caster as quickly as possible, as they and Tsathoggua are always interested in meals, new worshipers who might bring further meals, or just having a good time toying with fragile humanoids.
If this ritual is cast in or within 90 feet of any temple of Tsathoggua (even one without an intact altar or statue of Tsathoggua), the range becomes unlimited.
