Initiative in D&D: How It Works, Bonuses, and Tracking It

Initiative is the roll that decides who acts first when a fight breaks out. If you searched for initiative DnD rules because the word was thrown at you mid-session, you are in good company: it is probably the first rule a new player meets without fully understanding it. The DM says 'roll initiative', everyone rolls a d20, numbers get called out, and somehow an order appears.

Here is the whole thing, from the number on your character sheet to the awkward moments at the table, with every rule stated for 5e and marked where the 2014 and 2024 rulebooks disagree. Beginners first, DMs at the end.

What Initiative Is and How It Works

Combat in D&D runs in rounds, and a round is everyone taking one turn. Initiative decides the order of those turns, and it is set once, at the start of the fight, then kept for the whole battle.

When combat begins, every participant makes an initiative roll: a d20 plus their initiative modifier. The DM lists everyone from the highest result to lowest, and that list is the turn order. The highest roller acts first, then the next, and so on down to the lowest. When the lowest has finished, the round ends and a new one begins at the top of the same list.

Three things about DnD initiative trip new players up. First, you roll initiative once per fight, never once per round. Second, monsters roll too, and they slot into the same list as the players. Third, your position in the order is fixed for the fight unless a specific rule moves it, which we cover below. That's it. Everything else about 5e initiative is detail on top of that one list.

How to Determine Your Initiative Bonus

If you are wondering how to determine default initiative in DnD, the answer is short: your initiative modifier is your Dexterity modifier. That is the whole formula for most characters. No class adds to it by default, no race changes it, and you do not add your proficiency bonus, because initiative is a Dexterity check rather than a skill or a saving throw.

Your Dexterity modifier comes from your Dexterity score. Subtract 10 from the score, divide by two, and round down. So a Dexterity of 16 gives a +3, and that +3 is your initiative. On a paper character sheet it sits in its own box, usually near Armour Class and Speed. On D&D Beyond it is shown at the top of the sheet beside the other combat stats, already calculated for you.

A worked example: Mira the rogue has Dexterity 16, so her modifier is +3 and her initiative is +3. When the DM calls for initiative she rolls a d20, gets an 11, and adds 3 for a total of 14. If her sheet showed a higher number than her Dexterity modifier, it would be because of one of the bonuses in the next section.

Initiative Bonuses: What Can Raise It

The general answer to what raises an initiative bonus is Dexterity, first and overwhelmingly. Every two points of Dexterity are an extra point to your initiative bonus, and most characters never get anything else. A handful of well-known options add more:

The Alert feat. In the 2014 rules, Alert gives a flat +5 to initiative, and you cannot be surprised while conscious. In the 2024 rules it works differently: you add your proficiency bonus to initiative rolls instead, and you can swap your initiative result with a willing ally right after rolling, provided neither of you is incapacitated. Check which rulebook your table uses, because the two versions are not the same feat.
The Swashbuckler's Rakish Audacity (rogue subclass). Lets you add your Charisma modifier to your initiative rolls, which stacks with Dexterity.
Jack of All Trades (bard, 2nd level). Adds half your proficiency bonus, rounded down, to any ability check that doesn't already include it. Initiative is an ability check, so bards get a +1 bonus at level 2, which rises to +2 at level 9 and +3 at level 17.
Gift of Alacrity (1st-level spell, Chronurgy wizard). Lets the target add 1d8 to initiative rolls for eight hours.
Feral Instinct (barbarian, 7th level). Grants advantage on initiative rolls. Advantage changes your average roll rather than your bonus, but at the table it feels much the same.
Sentinel Shield (uncommon, armour). It grants advantage on initiative rolls and advantage on perception checks, plus +5 to passive perception. Being a magic item it is open to any class, not just the ones with an innate feature.

Is it worth chasing initiative? For most characters, no. Going first is nice, and for a rogue or a spellcaster who wants to control the battlefield early it is genuinely valuable, but a feat slot spent on initiative is a feat slot not spent on hitting harder. Dexterity does the real work, and it also improves your Armour Class and your ranged attacks, so it is the only initiative investment that pays for itself three times over.

Ties, Surprise and the Awkward Moments

Ties

When two combatants roll the same initiative, the rules leave the resolution to the DM. The common table methods are to compare Dexterity scores (higher goes first), to have the tied combatants roll off, or, for a tie between players, to let them decide between themselves. For a tie between a player and a monster, many DMs simply rule in the player's favour. Pick one method at your table and stick with it, because consistency matters more than which option you choose.

Surprise

Surprise is the rule that changed most between editions, so here is both versions. In the 2014 rules, a creature that fails to notice a threat at the start of combat is surprised, and a surprised creature cannot move or take an action on its first turn, and cannot take a reaction until that turn ends. The ambushers effectively get a free round. In the 2024 rules, surprise is simpler: a surprised creature has disadvantage on its initiative roll, and that is the only effect. No lost turn, just a worse position in the order. If you are joining a new table, ask which version it uses before you plan an ambush around it.

Joining a fight late

When a creature enters a combat already in progress, it rolls initiative when it arrives and takes its place in the existing order from the next round. A monster that bursts through the door in round three rolls, slots in, and acts when its number comes up. There is no special penalty for being late and no special bonus either.

Running Initiative as the DM

The scrap-of-paper problem is universal. Someone calls out a 23 after you have written the order, so you squeeze them in with an arrow. Round three, the rogue asks if they've acted this round, and you cannot say for certain. The ogre you placed behind the door has not had a turn since the fight began because the scrap never mentioned him. If the fight involves any of the hazards from our traps and environmental hazards guide, the room itself needs a turn as well, which is one more thing the scrap forgets.

A few habits fix most of it. Call turns one ahead: 'Mira, you're up, and Dorn, you're on deck', which gives the next player time to think and keeps the table from stalling. Group monsters of the same type onto one roll, which the rules explicitly allow and which turns a fight against eight goblins from eight turns into one. Write the order top to bottom before anyone acts, including every monster, and tick a box per creature per round so the question 'have I gone yet' always has an answer. And keep the pace up by giving a dithering player a gentle count; a round that takes twenty minutes is a round nobody enjoyed.

I ran a decade of fights on the back of receipts before admitting the system was the problem. We built an initiative tracker inside Dungeon Weave for exactly this job: the encounter is planned inside the storyline it belongs to, so the monsters are already there when the fight starts, and the order holds itself while you run the battle. Monsters can seamlessly join in mid-battle and the environmental hazards slot right in too. A D&D initiative tracker earns its place by making the bookkeeping disappear, so that what is left is the part of combat you actually enjoy.

FAQs

What do you roll for initiative in D&D?

A d20, plus your initiative modifier, which for most characters is simply your Dexterity modifier. Everyone in the fight rolls once at the start of combat, the DM orders the results from highest to lowest, and that order is the turn sequence for the rest of the battle. You never re-roll between rounds.

Does initiative use Dexterity?

Yes. For initiative DnD 5e uses a Dexterity check, so your Dexterity modifier is the baseline. It uses no other ability score by default, and it does not add your proficiency bonus unless a specific feature says so, such as the 2024 version of the Alert feat. Features like the Swashbuckler's Rakish Audacity can add a second modifier on top.

What is a good initiative bonus?

A +2 or +3 is typical for characters who invested moderately in Dexterity, and +5 from a maxed Dexterity of 20 is as high as the base number goes. Anything above +5 means a feat, a subclass feature or a spell is contributing. There is no bonus that guarantees going first, since the d20 swings by twenty points, so treat initiative as a lean rather than a lock.

Do all monsters roll initiative separately?

They can, but they don't have to. The rules allow the DM to make one initiative roll for a whole group of identical creatures, so all six wolves act on the same count. Most DMs do this to keep fights moving, and give unique monsters, like the pack's leader, their own roll. Either approach is correct; grouping is just faster.

Can you hold or change your place in initiative?

You cannot simply move yourself down the order. What you can do is take the Ready action: on your turn, you choose a trigger ('when the goblin comes through the door') and a response, then use your reaction to act when that trigger happens. The distinction matters: readying does not change your initiative count, it spends your action now in exchange for a reaction later, and if the trigger never happens, the readied action is lost. Readied spells also require concentration to hold. The one feature that actually moves you in the order is the 2024 Alert feat's swap with a willing ally, and that happens only immediately after initiative is rolled.

Roll Initiative

The number on your sheet is your Dexterity modifier, the roll is a d20 plus that number, and the order holds for the fight. Everything else is detail, and the DM's half of that detail is the part that gets lost on a scrap of paper. Dungeon Weave keeps the order with the encounter and the encounter with the story, and it's free to start. Go first, for once.
