Draconomorph

This spell transforms you into a new draconic form.

The transformation lasts for the duration, or until the you drop to 0 hit points. The new form can be any dragon (or any creature with the dragon type) whose challenge rating is equal to or less than your level. Your game statistics, except mental ability scores, are replaced by the statistics of the chosen dragon. You retain your alignment and personality.

You assume the hit points of your new form. When you revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn't reduce your normal form to 0 hit points, you are't knocked unconscious. In addition if you come out of your draconic form as a result of dropping to 0 hit points you gain 2 levels of exhaustion that last until you have completed your next long rest. 

You are limited in the actions you can perform by the nature of your new form, it can't cast spells that require somatic or material components, or take any other action that requires hands.

Your gear melds into the new form. You can't activate, use, wield, or otherwise benefit from any of your equipment.
