05. The Fame Boost

It is known that Servants, when in their native regions, gain a boost to their Parameters. In Fate/Apocrypha, Vlad III was noted to be quite mediocre when not in his homeland of Romania. Inside Romania however, he was able to keep up with the insanity of the Red Team. On Fate/Brave Shine, the fame bonus has been expanded somewhat. Rather than just the Servant's home country, it is instead expanded to the entire region. So instead of just Romania, Vlad gains his fame boost when in the entirety of Eastern Europe.

As noted, the fame boost is a boost to one's parameters, but how strong is it? It's only a single rank up. Let's say then that Artoria Pendragon's parameters are the following.

Strength: B
Endurance: C
Agility: C
Mana: B
Luck: B

Or that she has Shirou as her Master. Whatever. Anyway, then at some point, Shirou and Artoria both travel to Western Europe for some reason. So long as they are in Western Europe, Artoria's fame bonus would kick in, and she would receive a rank up to all her parameters until they left. Meaning that in Western Europe, her parameters are,

Strength: A
Endurance: B
Agility: B
Mana: A
Luck: A
