If you get a Passion award that raises your Loyalty by 30%. If you didn’t have that specific Passion earlier, what will your Loyalty be now?
If you already had a loyalty passion to the individual from other events, perhaps through other encounters, it would likely already be at 60%, so you would add the 30% directly, otherwise use the guidance on page RuneQuest Glorantha 236-237. If you wish to even take the loyalty, it could range anywhere between 60 and 90%. Review the adventurer’s relationship and interactions with the individual and make the decision from there.
Remember that Loyalty (individual), is also used to gain the personal support of that individual.
