lemme ask a "bad RDM" question.

how, exactly, does Diversion work? I use it whenever I see yellow on my enmity list, but i've never been sure exactly how it functions.

is it an instant decrease in emnity? is it gradual, reducing a set amount of enmity over time? or does it just cause your spells to generate less aggro for the duration?

I use Lucid Dreaming for MP recovery, the enmity decrease I consider a bonus. perhaps I should not use it in this manner.
