Spellsplinterer

Prerequisite:  Proficiency with a martial weapon

You have learned a long-forgotten martial technique from a faraway land used to fight magicians, gaining the following benefits:

• When an enemy casts a spell that takes one action or bonus action with verbal and somatic components, you may use your reaction to make a melee attack on them with your weapon if you are within range.

• Whenever you hit an enemy with an attack using your reaction and they are casting a spell using an action/bonus action, you may make a strength check. The DC for the check is equal to 10 + the spell's level (cantrips count as level 0). On a success, the spell fails to take effect but still consumes a spell slot.
