Some abilities are critical for removing game breaking strategies. However most of them are only available for the Unseen. I propose that each cult class has an ultimate that can only be used once per class (so if a seeker uses his ult then no other seekers can)
Seeker:
Day Ability: Mind Wraith - Immediately learn target player’s class and get a copy of their logs (1 use)
Invoker:
Day Ability: Weaken - If the Cult Leader attempts to erraticate target player then the erraticate cannot fail on them. (1 use)
Ritualist:
Day Ability: Shroud - If target player dies today or tommorow they will appear as the class of your choice (1 use)
Apostle:
Passive: Astral - Until an ultimate is used your ability’s do not count as visiting
