Fate/Extella Link is the sort of game with lots of options in front of the player. As someone goes through the adventure, they can eventually end up with 27 playable characters. It is a lot to take in. A newcomer might wonder which Servant might be most suitable for certain situations or best suit a person’s style. Fortunately, each one has a sort of niche they fill due to their class, and they also have active skills that can be changed to make them even more accommodating.
