Dungeons & Dragons 5e Element 133 Class Feature: Ability Score Increase

You may choose to either;

• Boost One Ability Score By Two: This option lets you increase a stat to a new modifier immediately, to a max of 30. This is great for boosting your class’s primary ability score.
• Boost Two Ability Scores By One: If you have two odd ability scores, this option lets you round those two stats to an even number and max of 20, increasing the modifier of those stats.

You may only take this feature once at each tier it appears, including multiclasses. For example, you may not take this feature at Tier 9 for both your base class and your multiclass. You may take this feature in addition to the Ability Score Improvements feature granted by the General Class base class features.
