This spell gathers a small bit of matter from a creature against whom you make a melee touch attack. Such an attack does not provoke attacks of opportunity. For the duration of the spell and for so long as you possess the bit of matter, the creature touched suffers a -2 penalty on save DCs against your spells and spell-like abilities, and a -2 penalty on attacks against you.
