Ritualist
Pathfinder 2nd
An archetype that any class can take. With the GM's permission, you can circumvent doing side quests to learn rituals and be really good at casting them. You start with a +2 circumstance bonuse to pull off rituals and learn two uncommon ritual spell + 2 more at 8th, 12th, 16th, and 20th level. You then can gain feats to reduce ritual requirement: less secondary casters can cast even if one skill level lower then required, and turn a casting time of days to hours.
