Alternatives to Epic Boons
You might decide to grant one of the following rewards to a 20th-level character, instead of awarding an epic boon. These two options can be awarded to a character more than once.
Ability Score Improvement. The character can increase one ability score by 2 or increase two ability scores by l each. The ability score can now be increased above 20, up to a maximum of 30.
New Feat. The character gains a new feat chosen by the player, but subject to your approval.
