Roc Origamiracle

Fold into Existence. You can use an action to write the word 'Roc' on this paper using magical ink, in the Auran language. When you do, the paper magically folds and shapes itself into a small paper bird. You can use another action to speak a command word to make the tiny paper bird fly to a 20ft. by 20ft. unoccupied space within 90ft. of you where it then transforms into a full sized Roc made of paper.   This Roc is vulnerable to Fire damage but has all other statistics and abilities of a regular Roc. In combat it rolls its own initiative. It is friendly to you and your allies, understands your languages and obeys your spoken commands. If you issue no commands, the Roc defends itself but takes no other actions. The Roc exists for up to 10 minutes. At the end of the duration, or when the Roc drops to 0 hit points, the paper shreds itself into countless feather shaped pieces.
