Wondrous Item, Artifact, Weapon (Quarterstaff), Requires Attunement
Dwemer Staves are made of a unique alloy simply known as Dwemer Metal. Dwemer Metal is resistant to rust or acid corrosion. (This resistance does not extend to the wielder but simply reduces the damage the weapon would take from such effects.)
Autmatonomous: As an action, you can choose to summon a Dwemer Spider or Sphere to your side for 1 minute. The summoned Automaton appears within 30 feet of the caster. Once used, the caster must finish a long rest before using it again.
