Prepared tinder in a waterproof container, for the night it is not going well.

Gathering natural tinder works right up until everything is soaked, and then it does not work at all. This is the hedge against that: dry, treated tinder sealed away from the weather, ready to take a spark immediately.

Keep it in the recovery bag rather than the camp kit, and treat it as emergency stock rather than everyday fire lighting. Use fire sticks for a normal camp and save this for when you are cold and the weather has turned.
