As two actions, choose a creature, object, or magical effect within 36 meters. For each spell on the target, make an ability check using your spellcasting ability with a bonus equal to the mana or psi expended to cast this spell. The DC equals the creature’s spell DC + twice the spell’s effective mana. If you have identified the spell, you have advantage on this ability check.
On a success, the spell ends.
A spell’s effective mana is normally the amount of mana it was cast with, including augmentation. If a feature lets a spell be cast without expending mana then the spell’s effective mana is its normal mana cost.
You gain a bonus to your ability check equal to 2 for each additional mana or psi expended.
