Guild Wars 2

i chose Cantha as my heritage on the story completed all events and then talk to the Personal story Sister Deborah

it gave me three choices of Dialogue

Charm, Dignity and ferocity

you can choose each choice with unlimited uses and fill up any of the three Bars with just constant spammage, I don’t know if this is a bug or Dev design just thought I’d report it

It’s not a bug. You can do this many different places in the game.
