Raging Shield and shield slot

There should be a new slot called a shield slot. All players could equip a shield which provides extra shield health to your player. It would be able to tank damage until it broke, which then it would enter a cooldown state and damage would be directly taken to you. Shields would have fairly long cooldowns to provide for their immense protective capabilities. A shield could be broken by enough damage in one attack, but damage would not overflow to your health. The shield would eventually respawn and have to recharge its durability back up. While charging up, it would gain chunks of its durability back over a few seconds. The shield could be broken again while charging, and if it breaks it reactivates its cooldown. But if she shield is charging, it won’t stop charging until it breaks or hits full up again. Then, it won’t charge back up anymore unless it breaks, and respawns from the cooldown. I think this would lead to some cool enchantment options like shield charge, and new shield variants and enchantments.
