Apex is engaging someone who possesses the talent Causality Perception. She is able to perceive all cause and effect relations. She can notably deduce the path leading to any effect, allowing her to plan, analyze, and take action with absolute efficiency.
In a fighting situation, she can perfectly adapt to all factors before they even appear, achieving maximum efficiency in offense, defense, and strategy, ensuring optimal success as long as there is the slightest chance.

If you've noted my previous posts she generally chooses the defensive and evasive strategy, this is because she isn't strong or durable and it is the best use of the talent.

As Sun Tzu said "The supreme art of war is to subdue the enemy without fighting."
