Eggmorph

You target a creature that you can see within range and encase it in a magical egg. The target must make a Constitution saving throw. On a failed save, the creature is trapped within the egg and is considered restrained and its speed becomes 0. Any equippement that the creature is carying is falling on the ground near the egg.

The egg is of a size proportional to the targeted creature, has an AC of 15 and 20 hit points. If the egg is broken before the duration ends, the creature reverts to its original form at the spot, with the same number of hit points it had before it was transformed.

This spell has no effect on a shapechanger or a creature with 0 hit points. 

If the creature remains in egg form for a full 24 hours without breaking free, it hatches into a new form. After spending at least 1 hour in the egg An unwilling creature can make a Wisdom saving throw, and if it succeeds, it breaks free and reverts to its original form.

The target transforms into a creature, chosen by the caster, with a challenge rating equal to or less than that of the target. The creature retains its alignment and personality, as well as its Intelligence, Wisdom, and Charisma scores. It also retains all of its skill and saving throw proficiencies, in addition to gaining those of the creature of its new form.

The transformed creature reverts to its original form if it dies.
