Checks (Rules) (Player Core)

At the ritual's culmination, you must attempt the skill check listed in the Primary Check entry to determine the ritual's outcome. Primary checks usually have a very hard DC for a level that's twice the ritual's spell rank. As with other downtime activities, fortune and misfortune effects can't modify your checks for the ritual, nor can bonuses or penalties that aren't active throughout the process. The GM can adjust the DCs of rituals, add or change primary or secondary checks, or even waive requirements to fit specific circumstances. For example, performing a ritual in a location where ley lines converge on the night of a new moon might make a normally difficult ritual drastically easier.
