Your Arrow points to Permanent Effect, it's like the Harpy's Level 10 Cloud Cover, gives your Shelter an additional +50,000, it upgrades as your skill upgrades, where as Support Skills Regenerate over a period of time, the higher the level the less time. As we have the new Sigils Research Line, this may increase the amount of Leaders being deployed, and possible captured, the Prison Break Ability will not be something you can click on and use, but instead after capture, while waiting in jail, the leader will have an increased chance of successfully escaping the prison +2%, - and +10% at Level 10 skill. But it's just easier to buy a devils cap and revival fruit. And place your interest into Convocation.
Hope that helps, Beerwizard.
