Rituals
Rituals will be learned using these steps and are for ALL blood sorcery (Thaumaturgy, Necromancy, Dur-An-Ki, eetc):
There are two ways that the ritual can be learned:
If your character is in good standing with the clan that teaches it (ex. a loyal Tremere or Giovanni), then they may simply request to have the ritual taught to them and after the lesson may move on to the Mastery rolls.
If they are unable to gain approval, or would prefer to simply research it on their own then the following rules apply for researching it. They must make an extended Intelligence + Investigation roll with difficult of ritual's level +3. The number of successes required is equal to the ritual's level x3. The roll can be made once every number of days equal to the rating of the ritual. So for example, with a level 3 ritual you could roll for it once every three days.
After they have finished learning of the ritual by either method, they must then master it. This will require an extended roll of Intelligence + Occult with a difficulty of the ritual's level +3. The number of successes needed is equal to the ritual's level x3. The roll can be made once every number of days equal to the rating of the ritual, same as during the research phase.
Your mentor rating can be added to the number of dice available for your roll.
Note Diablorizing a vampire with these disciplines do not grant the Kindred automatic access to the rituals. you will still need learn the rituals this way and that is IF you get a mentor for the Discipline.
