The Charisma (CHA) attribute directly impacts the chances of achieving critical hits in combat or provoking critical actions outside of combat.
Critical outcomes can yield advantageous effects if they result in a critical success, and conversely, create disastrous situations in the case of a critical failure.
The role of charisma in critical hits can be explained by the fact that charismatic individuals have an innate talent for influencing the course of events. Their self-confidence can generate moments of great success (critical success) or conversely, create disastrous situations (critical failure).
Negative CHA and Critical Failure
A negative CHA modifier increases the critical failure threshold on a D20 roll. Here is the corresponding table:
| CHA Value | Critical Failure on D20 |
|---|---|
| -4 | 3 or less |
| -3 or -2 | 2 or less |
| -1 or +0 | 1 |
Positive CHA and Critical Success
A positive CHA modifier reduces the critical success threshold on a D20 roll. Here is the corresponding table:
| CHA Value | Critical Success on D20 |
|---|---|
| +0 or +1 | 20 |
| +2 or +3 | 19 or more |
| +4 or +5 | 18 or more |
| +6 | 17 or more |
However, in combat, the total attack test result must be equal to or greater than the enemy's defense to benefit from bonus damage.
If, thanks to your CHA bonus, you inflict a critical hit but the total value of your test is less than the enemy's defense, although your action will be considered successful, you will only inflict normal damage.
