Mental Deflection

When a foe Casts a Spell that has the mental trait and you can see or otherwise detect its manifestations, you use your psychic powers to disrupt it. You expend 1 Focus Point to counter the triggering creature's casting of the spell. You then attempt to counteract the triggering spell using your spellcasting attribute modifier plus your spellcasting proficiency bonus as your counteract modifier and half your level, rounded up, as your counteract rank.
