Heartiel Action (ハーティエルアクション Hātieru Akushon?) is Shiny Luminous' only attack performed without the cooperation of Cure Black and Cure White. It can temporarily freeze an enemy and restore Pretty Cure's power, but is unable to purify it.
Shiny Luminous looks up at the sky and a giant heart slowly moves towards her. It shrinks and becomes the Heartiel Baton. Using this, she puts it before her, making it float in the air, before again touching it to let a wave of light shoot from it and onto the enemy or Pretty Cure, temporally freezing the enemy or giving Pretty Cure their powers back. This attack is also used in Pretty Cure All Stars DX 2: Kibou no Hikari - Rainbow Jewel o Mamore! and Pretty Cure All Stars DX 3: Mirai ni Todoke! Sekai wo Tsunagu Niji☆Iro no Hana.
