Instinct

The first time per encounter that you are attacked by a Stealth attack, that attack does not gain the Trick Attack benefit. If you become the target of an attack while you're surprised, you may still react to it and any special properties of an attack that require you to be unaware of the attack (such as Killshot) do not apply to it. 

In addition, when you are about to take an action that leads to grave harm or death (example: The enemy has an instant death ability), you can receive a premonition from the DM.
