There are five stats for all characters whether Servants or Masters. There is Strength, Mana, Endurance, Luck, and Agility. There is one class special to Servants and that is Noble Phantasm.
Each stat is ranked from E to A, E being the lowest ranking obviously. Rankings can also have a - and up to 3 +s. A plus represents that if certain conditions are met the stat is greater. One plus represent double and two triple and three four times as much. Meanwhile a - means that the stat is lesser than that without but still greater than that of a lower rank.
There is also a ranking given to those who stats are significantly off the scale known as EX. EX rankings are so powerful that they are literally in a league of their own.
In this Rp you need to write 300 sentences to upgrade up a rank in a stat. However, for every 200 words you post you get a point. Points will be explained in more detail later but they can be used to upgrade your character as well.
