Request for clarification: the Whisper’s Tempest ability.

Request for clarification: the Whisper’s Tempest ability. Page 61 says “Every PC can roll their ATTUNE rating to attempt arcane actions, even if they’re not specifically a trained ‘Whisper.”” The page then goes on to list examples of various arcane effects at the various stress levels.

The rules are ambiguous here — is the Whisper’s “Tempest” ability required to produce flashy, overt effects, or no? The rules on page 61 seem to imply that it is not, but that would make the ability itself useless.

I understand that any playbook can take Tempest as a veteran ability, but the powers it opens up should be made more explicit.
