I wonder if the parameters only affect hidden numbers, or if they do base Attack and HP (in combination with rarity and Class of course). If the former, I bet STR affects NP gain from attacking, and END affects NP gain from taking damage (unless there's a natural balance between the two). By process of elimination AGI would affect star absorption. And it kinda makes sense right? I mean, Riders usually have high Agility and they are this game's crit machines.

Very interesting read nonetheless. All these times we thought Parameters were just for show lol.
