Granting Abilities

You can grant an ability before the ASC was initialized with an avatar and owning actor. Abilities are stored in ActivatableAbilities.

Custom Gameplay Effect blocking

You can use GameplayEffectApplicationQueries (see UImmunityGameplayEffectComponent for an example) to block GEs that are about to be applied.
