True Counterspell

   You attempt to assume control of a spell in the process of being cast. If the targeted spell is cast at 5th level or lower, you now control the spell and can target any creature or area allowed by the targeted spell as if cast by you. If the spell is of 6th level or greater, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level if the spell is not known by the caster, or 8 + the spell's level if it is. On a success, you now control the targeted spell. The controlled spell uses your stats to determine Spell Save DC and Hit Modifiers if applicable.

   If the targeted spell is a concentration spell, you will maintain concentration as if they cast the targeted spell. If this spell is cast while concentrating on a spell, the caster will have the option to stop concentrating on the spell and begin concentrating on the targeted spell, or maintain concentration on the spell and dispel the targeted spell as if counterspell was cast.

   At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the target spell is controlled if its level is one less than or lower than the level of the spell slot you used.
