Monks of the Moon are fierce guardians of the wilds. Their monastery gathers under the full moon to share news and trade warnings. They haunt the deepest parts of the wilderness, where they might go for weeks on end before crossing paths with another humanoid creature, let alone another Monk.

Changeable as the moon, a Monk of this monastery might prowl as a great cat one night, soar over the treetops as an eagle the next day, and crash through the undergrowth in bear form to drive off a trespassing monster. The wild is in the Monk's blood.

Wild Shape

Starting at the 3rd level, you can use your action to spend 3  Ki points to magically assume the shape of a beast that you have seen before. You can use this feature number of times equal to half your proficiency bonus (rounded down). You regain expended uses when you finish a short or long rest.

Your Monk level determines the beasts you can transform into, as shown in the Beast Shapes table. At the 3rd level, for example, you can transform into any beast that has a challenge rating of 1/4 or lower that doesn't have a flying or swimming speed.

While you are transformed, the following rules apply:You can stay in a beast shape for a number of hours equal to half your Monk level. You then revert to your normal form unless you expend another use of this feature. 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.

• Your game statistics are replaced by the statistics of the beast, 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 beast'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 animal 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.
• You can't cast spells, and your ability to speak or take any action that requires hands is limited to the capabilities of your beast form. Transforming doesn't break your concentration on a spell you've already cast, however, or prevent you from taking actions that are part of a spell, such as call lightning, that you've already cast.
• You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can't use any of your special senses, such as darkvision, unless your new form also has that sense.
• 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.
• MONK: When you use Monk features in your Wild Shape form you can use certain attributes of the beast you are using like reach and damage type
