Backlash: The primary caster takes 2d6 points of damage and becomes exhausted. The secondary casters become fatigued.
Failure: A zuishin appears and attacks all of the casters until the zuishin or the casters are destroyed. Afterward, all kami completely ignore the casters for 1 year and will not answer to any ritual in which any of those casters are involved.
The primary caster appeals to a local kami to ask for assistance in battle. The casters must assemble a shrine within 100 feet of the kami’s ward. Once the ritual begins, the casters each utter a unique prayer to the kami, complete with devotionals and explanations about why the kami’s help is needed. If the casting is successful, the kami manifests (as per summon monster V) and fights alongside the casters. This kami uses the statistics for a kodama and refuses to move farther than 1 mile from its ward.
