Disengage (Minor Action)
On your turn if you're in melee range of an enemy you can choose to use a minor action to attempt to move away from them with an opposed ability test. Ability (Focus) of your choice vs. their Dexterity (Initiative) against all enemies within range. On a success you're able to move away from your opponent before they get an opportunity to attack you. On a fail your opponent gets an opportunity to attack before you are able to move away from them.
Suggested Ability (Focus) to use when attempting to disengage are Constitution (Running), Dexterity (Acrobatics) and Dexterity (Initiative). If you choose different abilities and focuses the GM may require you to explain how you are using those skills in this instance and may deny it if you can't make a reasonable explanation.
If you choose to not spend a minor action attempting to disengage then any enemies within melee distance get an opportunity to attack you before you are able to move away.
