What Is a Monk in D&D 5e?
A monk is a martial artist who has given up every advantage the rest of the party pays for. No armour, no spell list, no heavy weapon — the class is written so that a character with empty hands and a d8 hit die is still a threat. Unarmored Defense and Martial Arts arrive at 1st level, Ki and Unarmored Movement at 2nd, your Monastic Tradition and Deflect Missiles at 3rd, Slow Fall at 4th, and then the level that changes everything: Extra Attack and Stunning Strike together at 5th.
Martial Arts is the engine, and it runs for free. Your unarmed strikes and monk weapons use Dexterity and a martial arts die that grows as you level — an 11th-level monk is rolling a d8 — and every Attack action hands you a bonus-action unarmed strike at no cost at all. Stack Extra Attack on top and a 5th-level monk who spends one ki on Flurry of Blows is making four attacks in a turn, at a point in the game where most martials are making two.
Ki is what sits above that floor. Your pool equals your monk level, it comes back on a short rest rather than a long one, and Wisdom sets the save DC for everything you spend it on. In the late game the class stops being fragile in a way nothing else matches — Evasion and Stillness of Mind at 7th, Purity of Body at 10th, and Diamond Soul at 14th, which gives you proficiency in every saving throw in the game. Getting there is the hard part.
How Do Ki Points Work, and Why Do They Run Out So Fast?
Your ki pool is exactly your monk level. A 3rd-level monk has three points; a 10th-level monk has ten. That is a smaller number than it sounds, because almost everything the class wants to do costs one of them, and the pool refills on a short rest rather than a long one. No other class keeps its whole toolkit behind the party agreeing to stop for an hour. A day with two short rests in it is a different class from a day with none, which makes this a conversation to have with your DM at character creation rather than at 7th level.
The moment-to-moment version of the problem is a three-way choice you make every single turn, all funnelled through one bonus action. Flurry of Blows buys two more unarmed strikes. Patient Defense takes the Dodge action, so everything swinging at you does so at disadvantage. Step of the Wind Dashes or Disengages, which is how a monk crosses a battlefield or walks out of a bad position without being punished for it. One bonus action, one point, three answers — and reaching for Flurry every round is the most common way a new monk ends up empty before the second fight.
Then Stunning Strike draws on the same pool without asking for the bonus action, which is where the arithmetic really bites: a 5th-level monk holds five points, and one Flurry turn plus three stun attempts is the entire day. The discipline the class actually teaches is spending nothing. That free bonus-action strike from Martial Arts costs zero ki, so a monk cruising through a corridor fight on Attack-plus-free-strike is still pulling their weight — and arrives at the thing worth stunning with a full pool.
How Does a Monk’s Armour Class Work Without Armour?
Unarmored Defense sets your armour class at 10 plus your Dexterity modifier plus your Wisdom modifier, and only while you are wearing nothing. Put armour on and you do not merely lose the calculation — Martial Arts switches off with it, and Martial Arts is the class. The suit of plate the party drags out of the hoard is not an upgrade you are declining for flavour reasons; it is an item that would turn your damage off.
What makes this harder for a monk than for anyone else is that your armour class is a bill split between two different abilities, and both of them are already spoken for elsewhere. Dexterity is your attack roll and your damage. Wisdom is your Stunning Strike DC. Neither is a defensive stat you can quietly overfund, because every point of armour class comes out of the same budget as your offence — and until both numbers are high, your sheet reads: no armour, a d8 hit die, and a middling AC standing in the front rank.
So the class does not defend by raising the number. It defends by not being where the attack lands. Patient Defense converts a bonus action into the Dodge action, the strongest defensive button any martial can press on demand. Step of the Wind and Unarmored Movement mean you can be somewhere the enemy has to spend a turn walking to. Deflect Missiles from 3rd level takes the sting out of the archers who punish a low-AC skirmisher, and Evasion at 7th turns area damage into a Dexterity save you were going to make anyway. For gear, look at Bracers of Defense, a Cloak of Protection, or the Kensei’s free +2 armour class on any turn you attack — every point has to arrive from somewhere that is not armour.
What Are the Best Stats for a Monk?
Dexterity, then Wisdom, then Constitution — and the honest answer is that you want all three at once. Dexterity is your attack roll, your damage and half your armour class. Wisdom is the other half of that armour class and the save DC on every ki ability you own, Stunning Strike first among them. Constitution is what keeps a d8 hit die upright in melee range. Strength, Intelligence and Charisma are all genuinely skippable, which is the only mercy on the list.
This is the monk’s real problem, and the table name for it is MAD: multiple ability dependency. Most classes have one number that has to reach 20 by the mid-game and everything else is decoration. A monk has two, and neither is optional in the way a second stat usually is. Let Wisdom slip and your armour class drops while bosses stop failing the stun — the two things you are at the table to do. Let Dexterity slip and you stop landing the hit that Stunning Strike rides on in the first place. Every ability score improvement is therefore spent before you receive it, which is precisely why fitting a feat into a monk is so awkward.
There are two ways out of the squeeze inside the build itself. The first is Way of the Astral Self, whose spectral arms attack using Wisdom, so Dexterity falls back to being armour class only and the competition simply stops. The second is Resilient (Wisdom), the half-feat that buys half an ability score and a save proficiency out of a single slot — as close as this class comes to being handed an improvement back. Everything else depends on starting from a lineage that pays more than one of your three bills, which is the next question.
What Is the Best Race for a Monk?
A rogue needs one ability score. Any lineage with +2 Dexterity answers that question completely, and whatever else it brings is decoration. A monk is graded harder, because Dexterity and Wisdom both have to be high before the character functions — one carries your attacks, the other carries the DC you are asking bosses to fail — and Constitution still stands behind a d8 hit die. So the question is not which lineage is strongest, but how many of those three bills it pays for free.
Wood Elf is the textbook chassis: +2 Dexterity and +1 Wisdom is the rare line that funds both halves of the class at once, and it brings a 35-foot base speed and Mask of the Wild on top. Hill Dwarf answers from the other end with +2 Constitution and +1 Wisdom — no Dexterity at all, so you trade a fast start for a durable one, but Wisdom is still buying two things and Constitution smooths over the tier where monks fall down easily. Variant Human names no useful ability line and is a serious pick anyway: a feat at 1st level puts Mobile or Alert on a sheet whose improvements are spoken for years in advance.
The pure-Dexterity lineages are narrower, not weak — Lightfoot Halfling’s +2 Dexterity and +1 Charisma is a single-stat line for a class that dumps Charisma, but Lucky and Naturally Stealthy suit a Way of Shadow infiltrator, and Kobold adds Pack Tactics for advantage on a flank. If your table uses the newer option where ability increases float freely, that helps a monk more than almost anyone: a rogue was never constrained, since one +2 always landed in the right place, while a monk was picking from the short list that covered two stats. With floating scores you shop for traits instead.
How Does Stunning Strike Work?
From 5th level, when you hit a creature with a melee weapon attack, you can spend 1 ki point and force it to make a Constitution saving throw against your ki save DC. On a failure it is stunned until your next turn. Stunned is one of the harshest conditions in the game: the creature takes no actions and cannot move, it automatically fails every Strength and Dexterity saving throw, and every attack roll made against it has advantage.
Read that list again from the party’s side of the table, because it explains why a monk’s damage column undersells the class so badly. A stunned dragon does not act, so you have deleted a turn from the creature with the most dangerous action economy in the room. Every ally then swings at advantage. And those auto-failed Dexterity saves mean the wizard’s area spell lands at full effect on the one target it was never going to land on. A single ki point can be worth more than the rest of the party’s round put together.
The cost is that it is a saving throw, and the creatures most worth stunning tend to be the ones with the best Constitution. A failed attempt is a point gone for nothing, which is why stun-fishing pairs with volume: on a turn you have already committed, Flurry of Blows buys more hits and therefore more attempts. Alert helps you take the first attempt before the boss has had a turn at all, and Lucky earns its place for the same reason — a reroll can turn the save the boss made into the save it did not. And because the DC keys off Wisdom, this one feature is the whole argument against ever treating Wisdom as a monk’s afterthought stat.
What Is the Best Monk Subclass?
You choose a Monastic Tradition at 3rd level, and it decides what your ki turns into rather than how much of it you get. Six are laid out on this page. Way of the Open Hand is the oldest and still one of the strongest: its Open Hand Technique lets each Flurry of Blows punch knock the target prone, push it 15 feet, or deny it reactions, turning a damage button into a control button at no extra cost. Way of Shadow is the ninja — teleport between patches of darkness for 2 ki, with Darkness and Pass Without Trace attached — and it is the best infiltrator the class has.
Two traditions exist largely to solve the monk’s missing ranged option. Way of the Kensei lets chosen weapons use your martial arts die and hands you a free +2 armour class on any turn you attack, so a monk can fight with a longbow without leaving the class behind. Way of the Sun Soul replaces the attack itself with a ki-fuelled radiant bolt and adds a burst that lights up a room. If your table plays outdoors, at range, or against things that fly, one of these two is doing work the base class cannot.
The remaining pair are specialists. Way of Mercy is the only monk that keeps other people alive — Hand of Healing and Hand of Harm fold healing or necrotic damage into the Flurry you were making anyway. Way of the Astral Self summons spectral arms with extra reach that attack using Wisdom, the cleanest fix for the class’s stat problem anywhere in the list. Only part of this lineup is free-SRD material, so confirm exact wording and numbers in whichever book a tradition was published in before you build a character around it.
What Are the Best Feats for a Monk?
Start from what a feat costs a monk specifically. Your ability score improvements are already promised to Dexterity and Wisdom, and skipping one delays your armour class and your Stunning Strike DC in the same breath. The bar is therefore higher here than for a martial with points to spare: take a feat only if it does something ki cannot buy, or if it hands part of an ability score back to you.
Mobile is the signature pick. It adds 10 feet of speed to a chassis that already has Unarmored Movement, and it stops opportunity attacks from any creature you struck this turn — which converts hit-and-run from a gamble into a guarantee and, just as importantly, saves the ki you were otherwise spending on Step of the Wind every round. Alert is the other near-universal choice: +5 initiative and immunity to surprise means you land the first Stunning Strike before the boss has taken a turn to lose. On a class whose best feature deletes turns, going first is worth more than it is to anybody else.
After those two, pick for the seat you fill. Sentinel makes your opportunity attacks stop movement and punishes anything that swings at an ally, which pins down the target you most need held. Resilient (Wisdom) is the efficient compromise — half a feat and half an ability score, raising your armour class and stun DC while shoring up the save that removes fragile characters from fights. Lucky is three rerolls a day and does double duty here: force the Constitution save you needed the boss to fail, or rescue yourself from the hit that would drop you behind a d8 hit die.
What Are the Best Monk Multiclass Builds?
Monk dips should be short, and the reason is specific rather than a general caution. Your ki pool is your monk level, your martial arts die grows on monk levels, and Extra Attack and Stunning Strike both land at monk 5 — the single biggest level in the class. Every level spent elsewhere pushes all four of those back at once, on a character who is already thin through the early game. Then there is the stat problem underneath it: multiclassing carries ability score requirements, and a monk has no spare points to meet them with.
One or two rogue levels is the cleanest fit, because everything it gives you runs off the Dexterity you were maxing anyway. Expertise sharpens skills the monk was already first to reach, Sneak Attack adds damage to a finesse hit, and Cunning Action grants a bonus-action Dash or Disengage — which is Step of the Wind without the ki cost, freeing those points for stunning. A cleric dip is the other natural one: Wisdom already runs your armour class and your save DC, so one or two cleric levels buy genuine spellcasting off a stat you were forced to invest in regardless.
The combination that looks perfect and is not is monk and barbarian. Both have Unarmored Defense, so the pitch writes itself — but rage locks out spellcasting and concentration, the two classes pull toward different third stats, and a raging character is not the one who wants to spend bonus actions on Patient Defense and ki tricks. The two chassis compete for the same actions all combat. It makes a fun character and a poor build; pick the one you actually want to play and go deep on it instead.
Are Monks Weak in 5e?
The complaint is real and worth stating plainly. A monk has a d8 hit die and no armour, needs Dexterity and Wisdom and Constitution out of one budget, and burns through a ki pool the size of its own level. On raw damage it does not out-hit a great-weapon fighter, and it does not match a rogue’s burst — the two characters it gets compared to most often. Levels 1 through 4 are genuinely lean: two to four ki points, no Extra Attack, and no Stunning Strike yet.
The case for the defence is that most of what a monk contributes never appears in a damage column. Stunning Strike removes an enemy turn and hands the whole party advantage against the target, and no quantity of extra dice is worth as much as a boss that does not act. Unarmored Movement and Step of the Wind mean you reach the caster at the back that nobody else can get to. Deflect Missiles blunts the archers, Evasion at 7th turns area spells aimed at you into a save you are built to pass, and Diamond Soul at 14th gives you proficiency in every saving throw — a defensive package no other martial ends up holding.
So the honest verdict splits by tier: weak early, excellent through the middle. What decides which of those you actually experience is not the build, it is the table. Ki refills on short rests, so a campaign that takes two per adventuring day gives you a monk operating at full strength all day, while a campaign that runs one long fight and then a long rest gives you a martial artist who is empty by round four. Ask before you roll the character. Then take Mobile, keep Wisdom climbing, and spend nothing until the thing worth stunning walks into the room.
