There are Hylian Shield replicas and then there are Hylian Shield Replicas. The one above fits into the latter and probably could've been used with a certain live-action Netflix series that sadly isn't happening. The team at Baltimore Knife and Sword makes all kinds of armaments for their YouTube series Man at Arms: Reforged, and their latest project is the perennial shield from Nintendo's Legend of Zelda series, along with what NeoGAF posits is a Link to the Past-styled Master Sword. The level of craftsmanship is what separates this gear from what you'd typically see cosplayers brandish at PAX; the Triforce is made of amber and the shield can even withstand a barrage of arrows.
All that to say, you could probably totally kill someone and successfully defend yourself against a moblin offing you with these. Whether or not you could bounce energy blasts back at their attacker and save the kingdom with this shield is anyone's guess, though. Need more?
