It is its own game. A roll under system with degrees of success.Are you building an OGL? 5RD? If not, we need to know what a save is and how it relates to most of your other combat rules.
To illustrate, I could tell you that Modos RPG characters can make three different "saves": Parry, Concentration, or Willpower. But you don't really know when to roll those, where the numbers come from, how to increase them, or how they differ from the Parry, Concentration, or Willpower defenses unless you know the other rules involved.
OK, cool. How is an Acumen save different from an Agility roll? Or, why can't an Acumen save just be an Agility roll?It is its own game. A roll under system with degrees of success.
So for a Save to succeed you need to roll under its Attribute Number.
Acumen is different as it encompasses your mind as well. Each save has two opportunities to make it good or great (I mean they could end up bad, too, if both Stats that happen to correspond with a Save are just really terrible), with Acumen using both Agility and Knowledge.OK, cool.

There are no Skills, just Stats and Saves.It worked in 3.5 and others but why saves at all? Why not a skill check or something similar.
