UPDATE: GM Tago announced an update to the Fire Spirit (111) spell: It is no longer possible to cast it without a target in an indoor sanctuary. It used to rebound, and you and your group took damage. However, you can still cast it without a target in an outdoor sanctuary to send a signal into the sky.

It is no longer possible to cast fire spirit (111) without a target in an indoors sanctuary. Previously, it was possible to trigger the rebound effect and damage both yourself and your group. It is still possible to cast fire spirit without a target in an outdoors sanctuary to send a signal up into the sky.
