Looking through the code of Big and Might Be Bad Wolf's EGO card; you could probably edit the code to fit as a Passive ability or attribute to a specific Dice on a page by using:
Removing "breakRate" from the original code keeps the Stagger damage dealt, but keeping the "dmgRate = -9999" means the dice played will do no HP damage.

Looking through the code of Big and Might Be Bad Wolf's EGO card; you could probably edit the code to fit as a Passive ability or attribute to a specific Dice on a page by using:

public override void BeforeRollDice(BattleDiceBehavior behavior) => behavior.ApplyDiceStatBonus(new DiceStatBonus() { dmgRate = -9999 });

Removing "breakRate" from the original code keeps the Stagger damage dealt, but keeping the "dmgRate = -9999" means the dice played will do no HP damage.

thank you, i'll give this a shot
