Danger Sense also gives a defensive boost, and the ability to reliably know where attacks will be landing a round in advance. For example, Niil will know that four shots will be fired at him, and where those shots will go, so he can strategically move to place equipment, or even pre-dodge those shots so they all miss.
In game terms, having Danger Sense up forces all opponents to declare their attacks a round in advance, and locks them in to those actions.
