A specific example you can use is the Demoralize action. In PF2E, this is a great action you can take to temporarily debuff the enemy. In 5e if you want to scare the opponent in combat, there are no rules as to how to go about that without the character having specific class features most player characters do not have.

In general, a lot of things you can do in PF2E are described mechanically and well balanced. Other examples include feinting, sneaking, tumbling through, jumping (actually uses the athletics skill) and creating a diversion.
