Party Ability

Equipping Vision Cards can have various effects, such as boosting the stats for all Units in your party.
*A vision card equipped to a sub slot bestows only a percentage of the Party Ability effects it would normally bestow from the main slot.
When two Vision Cards with the same effect are equipped, the effects are not stacked and the card with the higher stat is prioritized, regardless of activation conditions.
If your Companion (Friend or Trial) has the same effect as their party ability, then the effect is stacked.
