Stacking Unique Effects¶
The unique effects of different abilities are combined—effectively stacking on top of each other—if their durations and targets overlap. However, the effects of the same ability used multiple times don't stack. Instead, the most impactful effect—such as the highest bonus—from each use of the ability applies. The most recently used ability applies for determining duration.
For example, the null's Null Field ability reduces the potencies of enemies within the field by 1. If two allied nulls each have their Null Field ability active and an enemy cultist is targeted by both abilities, that cultist's potencies are reduced by 1, not by 2.
Different effects that impose the same condition (see Conditions below) don't stack to impose the condition twice. For instance, if a hero is targeted by numerous creatures whose abilities cause a target to become weakened (imposing a bane on the target's power rolls), the target isn't weakened twice to impose a double bane on those rolls. A character who is grabbed by an enemy can't be grabbed again by another enemy. The same holds true for game effects that aren't conditions. For example, if a hero is targeted by multiple abilities or effects that can halve their recovery value, the hero's recovery value is halved only once.
