I feel like this calls for a new monk subclass.
WAY OF THE MUSHROOM
Smash Attack: When you take this path at 3rd level, you gain the ability to jump a distance equal to your speed. Whenever you make an unarmed attack immediately after jumping at least 20 feet, add one of your martial arts dice to the damage of that attack. You can't gain this bonus damage more than once per turn.
Super Mushroom: At 6th level, as a bonus action, you can expend 3 ki points to grow as if you had cast the enlarge/reduce spell on yourself, choosing the enlarge option. You also gain temporary hit points equal to twice your monk level. The effect ends after 1 minute or when all of these temporary hit points are lost.
Fire Flower: At 11th level, whenever you could make an unarmed strike, you can hurl a globe of fire instead. Make a ranged spell attack. If you hit, you deal 2d6 fire damage. At 11th level, the damage increases to 2d8, and at 17th level, it increases to 2d10.
Starman: At 17th level, as a bonus action, you can expend 4 ki points to become immune to all damage until the start of your next turn. While under this effect, you can use Smash Attack any number of times per turn, and you do not have to jump to use it.
