Craft the shield
1. Open a crafting table.
2. Place wood planks and an iron ingot in the standard vanilla shield pattern. This is six planks with the iron ingot in the top middle slot.
3. Take the shield and put it in your offhand or hotbar.
With the pack active, the shield uses a custom 3D model instead of the flat vanilla one.
Watch the damage tiers
The pack has several shield models, called shield1, shield2 and shield3. They match different damage tiers. To see the shield change:
1. Take your shield into survival combat.
2. Block attacks from mobs so the shield takes damage.
3. Check its look from time to time. As it wears down, it moves to a more battered model.
Trigger the blocking visuals
1. Hold Right Mouse Button, which is the default use key, while the shield is equipped.
2. Your shield shifts into its blocking pose. Each tier has its own blocking version, such as shield1_blocking or shield3_blocking. A worn shield looks different when it is raised than a fresh one does.
3. Try this in third-person view (press F5) to get a full look at the model while you block.
