Counterspell

Level 1

Abjuration Arcane Wizard

Trigger: A creature Casts a Spell that you have prepared.

When a foe Casts a Spell and you can see its manifestations,
you can use your own magic to disrupt it. You expend a
prepared spell to counter the triggering creature’s casting of
that same spell. You lose your spell slot as if you had cast the
triggering spell. You then attempt to counteract the triggering
spell (page 458).
