Cognitive Concentration

The spell caster may cast a second concentration spell without breaking concentration on another spell that requires concentration. They may then maintain concentration on the second spell by spending an action every round on subsequent turns until the spells duration ends. The two spells must be different spells. If the spell caster does not have an action to spend on concentration, or they cast a third concentration spell, they may choose which of the two spells to drop. If the spell caster fails a concentration saving throw, they lose concentration on both spells.
