I've been attempting to claim heir to the throne of Aragon, which means I have to keep my prestige higher than theirs as I understand it. However, while I try as I may, somehow my prestige sometimes tanks. Is this due to loans? Stability? What are some strategies to make sure I get that throne?
Claiming the throne costs prestige, as does refusing to honor a call to arms. The best strategy to get the throne is to simply hire a strong (4+ star) advisor who will raise prestige/keep it high, and concentrate on keeping only one throne at a time.
