Esta questão é sobre a característica Fúria Sobrenatural do Caminho dos Sagrados Kin de Notas Perdidas de Xanathar para Todas as Coisas (um terceiro livro de festa que pode ser encontrado em dmsguild.com).

Supernatural Fury

At 3rd level, you can focus on the magic in your blood, allowing you to concentrate your rage into the ancient magic of your bloodline and enter a Supernatural Fury. You gain the ability to cast and concentrate on spells, even while raging, at the expense of your physical resistances.

When you enter your Supernatural Fury and you aren’t wearing heavy armor, the following benefits replace the benefits of the Rage feature:

• You gain a bonus to your AC equal to your Strength modifier (minimum of +1).
• You have advantage on Constitution checks and saving throws made to maintain concentration on a spell.
• You have resistance to magical damage and are immune to the damage type you chose from your Ancestral Origin.

Your Supernatural Fury lasts for 1 minute. It ends early if you're knocked unconscious or if your turn ends and you haven’t attacked a hostile creature, cast a spell, or taken damage since your last turn. You can end your Supernatural Fury on your turn as a bonus action.

Isso significa que o bárbaro Sacred Kin pode escolher entre entrar em uma fúria "regular" e uma fúria sobrenatural? Ou será que ele (do nível 3 em diante) só ganha os benefícios de Fúria sobrenatural, porque substitui completamente a "antiga" raiva que ele usou no Nível 1 e 2?
