From the Part the Mistveil release notes

Vengeful Apparition triggers when it leaves the arena (for example, when it is destroyed, when it is banished, etc.). Whether you control an Illusionist aura is checked on the resolution of the trigger.
This does not trigger if this is a defending card on a chain link then leaves the combat chain due to it closing or due to an effect.
An aura card with the action type played as though it were an instant does not cost an action point and can be played whenever the player has priority, otherwise it is still considered to be an action card.

Keyword notes

Ward X - If your hero would be dealt damage, prevent X of that damage and destroy this.

Ward is a static ability that generates a fixed-prevention effect.
The prevention effect is not optional. It applies whenever damage would be dealt to your hero.
If another prevention effect reduces a damage event to 0, the replacement condition is no longer met (damage would not be dealt), so Ward would not apply.
The prevention amount applies to a single damage event. The leftover prevention amount does not apply to any future damage that would be dealt to your hero.
If the damage prevention can not be applied due to an effect, the object with Ward on it is still destroyed as part of the replacement effect application.
