Save
A save is a term derived from "saving throw", a term originating from tabletop role playing games as a defensive check to see if a player will take or avoid a harmful effect. Saves are usually referred to in the context "a (attribute) save of difficulty (number)".
By default, this is a 1d201-20 (Avg: 10.5) dice roll that has the attribute's modifier added to the result. If this is greater than the difficulty specified, the "save" is successful and the attempted effect to apply will be ignored.
If a save is against multiple attributes, the best modifier is used.
Some saves are also modified by an attacker's attribute, which adds to the save difficulty.
Most saves fail when the game rolls a natural 1 (i.e. "critical failure") and succeed on a natural 20 regardless of difficulty and bonuses, meaning you always have at least a 5% chance of success and at least a 5% chance of failure.
Saves include "Vs." tagging to designate what kind of effect they are, so save modifiers can be provided for particular scopes. If any part of a save modifier's scope matches to a part of the save's Vs., the save modifier applies.
You can see the details of all saving throws performed in the game with the debug option "Show saving throw debug text".
