Most shields, at best, can only exert less than half the essence of the Fernan Shield Art, which means the Flying Shield Technique and the Wobbly Shield Technique. The former is simple enough: find a good angle and throw the shield like a boomerang. The latter is a bit more complex; you can refer to the Barrier Shield that Motan comprehended.
Only shields specifically crafted for the Fernan Shield Art can truly unleash the full power of the shield technique. Although Scarlett has two shields given to her by Duke Fernan, and the Diesel Family even has a simplified version of the production process (horse swapped), the quality of the shields is just average and they are particularly fragile.
But the advance compensation for this action, Scenery, is different. Though NPCs can't see system notes and don't know the historical background of this item, Scarlett is a professional and can tell at a glance how terrifying this seemingly unimpressive shield truly is.
