Counterseize

You attempt to interrupt a creature in the process of casting a spell, extracting the magic used in the process. If the creature is casting a spell of 5th level or lower, its spell fails and has no effect. If the spell is countered in this manner, you absorb the magic used by the caster for a short period of time. Within the next minute, you can cast the countered spell at the same level of the original cast without expending a spell slot.

If it is casting a spell of 6th level or higher, make an ability check using your spellcasting ability. The DC equals 13 + the spell's level. On a success, the creature's spell fails and the energy is still absorbed, granting you the ability to cast the countered spell at the same level of the original cast without expending a spell slot in the next minute.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used.
