You create a link between you and the creature in your book, sharing its abilities and memories with you
Its equipment appears on you if you choose to.
You can stay in the creatures shape for as long as you maintain concentration.

You can revert to your normal form earlier by using a bonus action on your turn.
You automatically revert if you fall unconscious, drop to 0 hit points, or die.

While you are transformed, the following rules apply:

• Your game statistics are replaced by the statistics of the creature, but you retain your alignment, personality, and Intelligence, Wisdom, and Charisma scores. You also retain all of your skill and saving throw proficiencies, in addition to gaining those of the creature. If the creature has the same proficiency as you and the bonus in its stat block is higher than yours, use the creature’s bonus instead of yours. If the creature has any legendary or lair actions, you can’t use them.
• When you transform, you assume the creature’s hit points and Hit Dice. When you revert to your normal form, you return to the number of hit points you had before you transformed. However, if you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. For example, if you take 10 damage in creature form and have only 1 hit point left, you revert and take 9 damage. As long as the excess damage doesn’t reduce your normal form to 0 hit points, you aren’t knocked unconscious.
• If you try to access the creatures memory, or use any of its abilities. you must succeed on a persuasion or intimidation check against the creatures insight check.
• You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature’s shape and size. Your equipment doesn’t change size or shape to match the new form, and any equipment that the new form can’t wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until you leave the form.
• For every hours that passes while in the creatures form. You must make a Charisma saving throw against a DC 5 + the number of times you used the creatures memory or abilities. On a faillure, you lose control of the link and the creature controls you as if under a Dominate Monster spell. You remain under that creatures domination for the same amount of time that elapsed before you made the save. Exemple... you stayed in the form for 2 hours, rolled the save and failed. you are dominated for 2 hours.
