Building a rogue, and the description tells me Key Ability should only be Dex, unless a Racket gives another option. I chose the thief racket, which should not provide any extra options, but when I go to select my Class Boost, which is also used to define the ability used for Class DC, I have the options of Strength, Dexterity, Intelligence, Wisdom, and Charisma.
Is this a bug/missing feature in Pathbuilder, or am I misunderstanding what it’s doing?
Is this just based on the player core or are you using a character builder app? Pathfinder generally provides a lot of flexibility in terms of which builds are viable. Without pulling out a book to check, I suspect that the “key ability” is more of a suggestion than requirement.
The app “Pathbuilder 2e”. My understanding is that every character has exactly one key ability, which is what your class DC is set by, and for spellcasters it’s how your spell DC is set. Some classes get multiple choices. For example fighters can be strength or dex based.
For rogues, my understanding is that all rogues have the choice of dex, but some of their rackets (their subclasses) grant an additional option. So a mastermind rogue can choose intelligence or dexterity as their key ability. But in Pathbuilder, a mastermind rogue can also pick strength, wisdom, or charisma. Which I don’t think they should be able to do, unless I’m missing some niche edge case rule.
