Alecto's Resourceful Revenants

Alecto's Resourceful Revenants summons a single roiling mass of bones of many different types, sizes, and species. They are not connected together as they would be in a typical skeleton, rather, they articulate together dynamically in unusual ways, forming an amorphous collection of bones.

The Revenants will not attack, injure, or restrain creatures. If they are attacked, or see others engaged in combat, they will retreat to a safe distance, taking care to avoid any hostile creatures as they do. Otherwise, they will obey any orders that you give them.

Faithful to the Blueprints The Revenants roll with Advantage to repair an existing structure.

Versatile Shape The Revenants can rearrange their component bones to mimic the necessary tools for each of their proficiencies, and other simple tools (e.g. shovels). At the DM's discretion, they can also serve to temporarily take the form of a piece of machinery, like the missing wheel of a cart, or a gear to drive a millstone. Though Large, they can fit through openings that would permit only a Medium or smaller size category.

Unquiet Dead When active, the Revenants make quite a rattling clatter. They automatically fail stealth checks.
