Why can servants be summoned as multiple different classes in Fate/ Grand Order? Well, that's what I'll be talking about in today's blog post! This question is actually rather simple to answer. A servant's class is based on their strengths in life. Because of this, some servants can be summoned as several different classes. For example, Astolfo can be a rider or a saber because he was a sword fighter and knight in life. I think this is rather interesting, and can be useful during the times when only one servant of each class can be summoned. I know this post isn't very long, but I wanted to talk about it to clear up any potential confusion. As always, I hope you all still enjoyed this blog post!
