The best tip I have for Seregios is to roll right after being hit by his claws/airblades. You can roll out of the animation that actually causes Bleeding. Also aim at his legs as much as possible to trip him. Using a Blast or Paralysis weapon might also make things easier, if you aren't already using one.
