Resolute Caster
Prerequisite: The ability to cast at least one spell.
Your magic takes on a life of its own when it matters most. Your spells with a duration of concentration remain in effect after you lose concentration until the start of your next turn. This is true whether you lost concentration from taking damage, from being knocked unconscious, or even from being killed. (In the case of your death, the spell ends at the point when your next turn would have begun, if you were alive to take it.)
