Conjure Iron Cobra

You conjure a spirit that inhabits an Iron Cobra that you create. The construct created by this spell disappears when it drops to 0 hit points or when the spell ends.

The Iron Cobra is friendly to you and your companions. Roll initiative for the construct, which has its own turn. It obeys any verbal commands that you issue to it (no action required by you). If you don’t issue any commands to it, it defend itself from hostile creatures, but otherwise take no actions.
The DM has the creatures’ statistics.
