Command Construct

You rewrite the commands of the creator of the analyzed creation. This spell targets one construct or a network of constructs that are designed to work as a unit. Lesser constructs will follow simple commands and will not make saving throws. More complex and intelligent constructs may make saving throws, but are also able to carry out more complex tasks. The construct cannot be made to harm itself or directly override its original commands or purpose. Once released from your control, the construct will remain neutral to you and your party unless you do something that conflicts with its operations aside from your mere presence. 

Failed takeovers may result in a hostile construct.

Use on non-hostile constructs has advantage to take command.
