Ironclad Bracers

Wondrous item, rare (requires attunement)

These steel-plated bracers infuse the strength of raw iron into your possessions. Any items you wear or wield are treated as though they are damage resistant and have their hit points doubled if they are already damage resistant. However, all your worn or wielded items are considered metal when determining the results of effects specifically targeting metal, such as the powers of a rust monster. If you have a mount, anything worn by your mount is affected the same way.

You may also transform yourself or your mount as iron body for up to 1 minute, or you and your mount at the same time for up to 30 seconds. Once this effect ends, it cannot be used again until the next dawn.
