Do class features with multiple parts count as 1 class feature to retrain or is each part it's own class feature requiring 5 days of retraining each?
For example, the Beastmorph archetype has the Greater Beastform Mutagen ability which replaces poison resistance +2, +4, and +6, as well as poison immunity.
Does this count as 1 class feature (it is all under one heading) for 5 days of training, or 4 class features for 20 days of retraining?
