You attempt to absorb a spell and bind it within your body. If the spell's 5th level or lower, the spell does not affect you, and for the next minute, you do extra force damage when you hit with a spell attack equal to twice the triggering spell's level. If the spell's of 6th or greater, make an ability check using your SAM with the DC equal to 10 + the spell's level, as when using counterspell or dispel magic. On a success, the spell doesn't affect you, and you do extra force damage when you hit with a spell attack equal to twice the triggering spell's level.

At Higher Levels. When you cast this spell using a slot of 6th or higher, the spell absorbed automatically increases by 1 for each slot above 5th.
