As a reaction, you attempt to steal the magic from a creature in the process of casting a spell. If the creature is casting a spell of 4th level or lower, its spell fails and has no effect. If it is casting a spell of 5th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and has no effect.

As an Action you can choose one creature, object, or magical effect within range. Any spell of 4th level or lower on the target ends. For each spell of 5th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a successful check, the spell ends.

You gain Sorcery Points equal to half the spell's level for any spells you successfully steal, rounded down, a minimum of 1. This cannot give you more points than your current maximum points.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you automatically end the effects of a spell if its level is less than or equal to the level of the spell slot you used.
