@@ninteythree93 You get it from skills or passives/supports. Base Don by itself can only get haste via clash wins using S1. Which, if you're not using solo, you can't hit 10+ speed needed for S3 unless you have the +2 max speed in mirror dungeon or some other thing boosting your speed by at least 2. Off the top of my head, the support passives that give haste I can remember are maid Ryoshu or Cinq Sinclair, or R Mersault. Shi Don just gets a crapload of haste from S2, and some from S1 in comparison.
