Kabr could probably take them 1v2 in the Vault of Glass, they might know the mechanics, but without Kabr's relic they're finished. He could lead them into the gorgon's labyrinth and have them erased from existence. Or just clense himself while the oracles kill them. Or one shot from the shield's super because as said in the lore it has the gorgon's power to erase, not destroy, the templar's shield is invincible, you don't destroy it you erase it. Or Kabr would -blam!-ing tear them in half and literally make a shield out of them.
