During the walk cycle animation for wands that have an additional shield on your left arm, your character's spine compresses very unnaturally such that the body becomes much shorter. It is not just a perspective thing. Once you notice it, it is impossible to unsee. Applies to the Loch and Key Blade, Divine Paradox Defenders, Algid Durvish Armaments, Frostbound Sword and Shield, and Phaeoah's Judgement Khopesh just to name a few.
