Tbh, there's nothing really important about "servants" and "servant classes" in this wiki.

A single ability that is considered the unit's most famous attack.

Lancer: Wielder of a spear
Archer: Wielder of a ranged weapon
Rider: Rides some vehicle or animal
Assassin: Based on stealth and hit-and-run tactics
Caster: Wielder of magic
