Until the Blind on Flash runs out. B)

I've seen some sick returns on this so far, for this reason. Before, you lead with multiple Flashes, screwing over the duration because of resist. Now, you can lead with 1 Flash, spam TE until the Blind wears off, then reapply.

It doesn't have an Enmity multiplier, but it doesn't need one with a Flash lead and Shield Oath, at least for a good few hits.
