The CHA attribute (Charisma) has a direct impact on the chances of scoring critical hits in combat or triggering critical actions outside of combat.
Critical results can lead to advantageous effects in the case of a critical success, and conversely, create disastrous situations in the event 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 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 modifier of negative CHA increases the critical failure threshold in 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
In the presence of a modifier of positive CHA, the critical success threshold in a d20 roll is reduced. 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 the context of combat, the total attack test result must be greater than or equal to the enemy's defense to benefit from bonus damage.
If, thanks to your CHA bonus, you score a critical hit but the total value of your test is lower than the enemy's defense, although your action will be considered successful, you will only inflict normal damage.
