Card Trivia

 This card's TCG name may come from 理力, a Japanese term for the concept of The Force as seen in Star Wars media. Its OCG name is Force.
The monster sucking the energy out of the Warrior resembles Zoa.


OCG Rulings

This card targets 2 face-up monsters on the field: Riryoku

This card cannot be activated if there are not 2 face-up monsters on the field.

Previously Official Rulings

This card halves the current ATK of the monster it targets.

If this card targets a monster that is affected by "
Shrink", its ATK will become half of the halved ATK, or 1/4 its original ATK. If a monster whose ATK is halved by "Riryoku" is affected by "Shrink", its ATK will become half of its original (printed) ATK.

Mentions in Other Rulings

Big Shield Gardna: A face-down "Big Shield Gardna" can only negate a Spell Card that targets 1 face-down monster, so it cannot negate "Riryoku"

Spirit Reaper: If "Spirit Reaper" is targeted by "Riryoku", it is destroyed, but the increase to the other monster's ATK lasts until the end of the turn as normal.
