Wondrous Item
Common
A functional mechanical arm that can replace a missing one. This works for either a biological creature or a construct. This item follows the rules for attunement, but doesn’t require an attunement slot once attuned. While attuned in this way, it functions the same as the limb it replaces. Additionally, this arm can house a one-handed melee weapon of your choice. This weapon can be swapped out as part of a short or long rest.
