Spell Shattering Strike

You strike a spellcaster and disrupt their control over magic, fracturing the power behind a spell and transforming the energy so it roots them to the spot.

When a creature you can see within your reach casts a spell, you can use your reaction to make a melee weapon attack against it. On a hit, the creature makes a Wisdom saving throw or the spell is interrupted (expending the spell slot) and it rolls 1d4 to determine how the fraying magic affects it:

1. The creature’s Speed is reduced to 0.
2. The creature becomes confused until the end of its next turn.
3. The creature has disadvantage on checks made to concentrate on spells until it succeeds on a concentration check.
4. The creature is stunned until the end of its next turn and rattled for the next minute.
