Dawn can sometimes disable a Ruin Guard.It can do extended damage against enemies and bosses with large bodies such as Azhdaha.It can knockback small enemies and large enemies like Mitachurls and Geovishaps, but not Automatons or Abyss Mages when they have their shields on.This can be used to defend Ley Line Monoliths by pushing back hordes of enemies from the monolith.Dawn provides a form of Crowd Control, useful in clumping and pushing away mobs.When Diluc's claymore is infused with Pyro after casting Dawn, even if one swaps to a different party member and swaps back to Diluc, the Elemental Infusion will remain for its intended duration.
