Occult Club Moment

An instance where something, usually an item, is presented conveniently just before it is required, as seen in the video game Dark Souls, where the Occult Club is given to the player before the exact type of boss that is weak to it.

Another example; when finding C4 or an RPG right before encountering a heavily armored vehicle in a shooter game.
