Book: Player’s Guide and any book with subclasses
Page: See below.
Question: What should we do if a level increase grants a subclass feature that gives the character a skill proficiency that they are already proficient in? Does the guidance from page 118 apply to subclasses or only to class, lineage, and heritage during initial character creation?
The Player’s Guide tells us how to handle duplicate proficiencies from the combination of class, lineage, and heritage during the initial character creation process from:
Player’s Guide – Pg. 118 - SKILL PROFICIENCIES
Each background gives you proficiency in two skills. If your character would already gain the same skill proficiency from their class, lineage, or heritage features, you can choose a different skill proficiency instead.
However, the Player’s Guide does not seem to address how to handle duplicate proficiencies from a subclass during character level up (at least not explicitly).
I’m hoping you can provide some clarity for what should be done if a character gains a proficiency through a subclass at 3rd, 5th, 11th, or 15th level that would duplicate a proficiency they already have. I see two options:
- Page 118’s entry above applies because a subclass is part of a class and therefore any subclass features that provide skill proficiencies already obtained would allow the player to choose a different skill proficiency of their choice instead.
OR
- The portion of the subclass feature granting the skill proficiency that would be doubled up is useless unless it is framed specifically to grant a different benefit. See my comment further down for a breakdown of the three ways features seem to phrased across ToV supplemental books. I am doubtful that this option is the correct one because part of the design principles behind ToV included making sure that every level up was meaningful and that there weren’t any “dead” levels.
