Heartiel Action (ハーティエル・アンクション Haateieru Akushon?) is Shiny Luminous's 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. Because Shiny Luminous is not a real Cure, this attack does have not "Pretty Cure" in the name, but rather "Luminous".

Luminous: Ruminasu! Haateieru Akushon!
Porun: "Repeal the power of darkness-Popo! I am sure you can do it, Luminous-Popo!"
Luminous: "Will of light, Give to me the power of courage and hope!"
Luminous: "Luminous Heartiel Action!"
Shiny Luminous looks up at the sky, and slowly, a giant heart is moving toward her. It shrinks and become the Heart Baton . Using this, she puts it before her, making it float in the air, before again touching it to let a wave of light be shot from it and onto the enemy or Pretty Cure, temporally freezing the enemy or giving Pretty Cure their powers back.This (other) attack is also used in Pretty Cure All Stars DX 2: Kibou no Hikari - Rainbow Jewel wo Mamore! and Pretty Cure All Stars DX3: Mirai ni Todoke! Sekai wo Tsunagu Niji☆Iro no Hana.
