Actually if you had enough real vault of glass no cheesed completions you would know that oracles hp increases the longer they are summoned into the world and like he said before since the foil has oracle disruptor if you shoot it right as it spawns it kills it in one hit, on hard and normal. But not all of us are good enough at the game to spawn kill oracles, stick to your weak sauce groups and stop posting bs lies on these forums.
