Description
You cause the targeted set of armor to fight against it's wearer. While it still provides defense, movement is inhibited greatly as the wearer needs to strain in order to move. The creature wearing the armor can make a Fortitude save each round on their turn as a free action. If they succeed, they ignore the penalties for one round.
The wearer of armor affected by this spell takes a penalty to their attack rolls equal to their armor's armor check penalty.
It's theorized that this spell was used to make hunting large creatures easier; It's unknown why a spell would need to be made specifically to target other humanoids.
When augmented
When prepared/cast as a level 2 spell, you may instead target a creature. A creature must make a Fortitude save each round or take a penalty to their attack rolls equal to half their natural armor bonus.
