Shields have been in all previous Zelda games, and it's not different here. Nintendo didn't dive too much into the various shields during its E3 demos, but we did learn a few things. Link will be able to take enemies' shields and use them for himself. In fact, early on in the demo Link killed some Bokoblins and stole a shield from one of the beasts. Unfortunately these shields are made out of wood and can be burned. Plus, they aren't all that durable so a few direct hits could shatter it.
A metal shield, such as the Traveler's Shield seen in some gameplay demos at E3, will serve much better. Although we saw a few attendees wielding this item, we never saw a pop-up box showing off its picture and stats. If you come across this information, be sure to let us know!
Boko Shield
Protection: 3
A shoddy shield made of tree bark. It’s not very durable, but it serves its purpose.
Pot Lid
Protection: 1
The lid of a large soup pot. It smells vaguely of chicken broth… Yum! It can take quite a beating before breaking.
Spiked Boko Shield
Protection: 10
A Boko Shield made of slightly stronger wood. It’s been reinforced with animal bones.
