During last session in a game that I GM, the party got ambushed by NPC monks leaping from the trees. They were hiding high up in very big Sawtooth Oak Trees, then jumped in a horizontal direction towards a flying PC warlock to attack him with their darts. The size of the trees – average height of 40-50 foot in this scenario – allowed the monks to run on some of the branches and/or tree trunk before jumping.
In the heat of the moment, the warlock player convinced me that jumping distance is only 10 feet when doubled, so they wouldn't be able to reach him with their attacks. It didn't make any sense to me in the moment, to have 50 feet of movement as a monk but not be able to jump further than 10 feet. But the party was already having a rough time, and I didn't want to slow down combat by looking it up, so I ruled in favour of the party.
Now, post-session, I'm looking into the Basic Rules:
Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump. When you make a standing long jump, you can leap only half that distance. Either way, each foot you clear on the jump costs a foot of movement.
This rule assumes that the height of your jump doesn't matter, such as a jump across a stream or chasm. At your DM's option, you must succeed on a DC 10 Strength (Athletics) check to clear a low obstacle (no taller than a quarter of the jump's distance), such as a hedge or low wall. Otherwise, you hit it.
When you land in difficult terrain, you must succeed on a DC 10 Dexterity (Acrobatics) check to land on your feet. Otherwise, you land prone.
Please take the following details into consideration when answering this question.
- has 50 feet of movement (base)
- has a Strength score of 16
- is able to run the required 10 feet
- takes Step of the Wind as bonus action
- saves the Action for attacking
Step of the Wind. You can spend 1 ki point to take the Disengage or Dash action as a bonus action on your turn, and your jump distance is doubled for the turn.
What is the longest distance the monk can jump within this framework?
