D&D 5e Leveling Guide & Level Chart
Your DM leans back, grins, and says the magic words: “Everyone take a level.” Now what? Leveling up in 5e is the best kind of homework — a few minutes with your sheet and your character comes back stronger, scarier, and more yours. Here is exactly what changes from level 1 to 20, the choices you actually make, and the questions every table argues about — and when you want to see a build at any level, the generator rolls a complete sheet in seconds.
How to level up: the 6-step checklist
When your DM calls it, walk your sheet through these six steps — ideally between sessions, not mid-fight (more on that below):
- Pick your class. Take another level in your class — or, if you meet the ability-score prereqs, branch into a second one. Most people stay single-class; if the itch hits, the multiclassing guide has the math.
- Add hit points. One new Hit Die. Roll it (+ your CON modifier) for the thrill, or take the fixed average (+ CON) for the safety — see Roll or average? below.
- Take your new class features. Open your class table and grab whatever the new level hands you, making any choices it asks for (your subclass usually lands at level 3).
- Update your spells. If you cast, check for new spell slots and spells — the spell slot calculator gives you the slot table, cantrips, and prepared-spell count for your class and level.
- Bump your proficiency bonus — at 5, 9, 13, and 17. When it ticks up, re-do every attack roll, save, and skill you’re proficient in.
- At 4, 8, 12, 16, and 19: ASI or feat. +2 to one ability, +1 to two, or a feat. Raise CON and your max HP goes up retroactively — +1 for every level you already have.
How you actually gain levels: XP vs milestone
There are two official ways to track progress, and tables argue about it endlessly. Experience points (XP): you earn points for beating monsters, disarming traps, or talking your way out of trouble, and you level the moment you cross a threshold (300 XP for level 2, 900 for level 3, and up). Milestone: the DM ignores XP entirely and levels the party when the story hits a beat — a boss falls, an arc closes. Most modern tables run milestone: no bookkeeping, no grinding kills for the last 40 XP, and the DM keeps the pacing. Both are legit — your DM picks one.
Proficiency bonus by level
Your proficiency bonus is added to attack rolls, spell save DCs, and any skill or save you’re proficient in. It is the same for every class:
- +2 — levels 1–4
- +3 — levels 5–8
- +4 — levels 9–12
- +5 — levels 13–16
- +6 — levels 17–20
Multiclassing? It scales with your total level, not any one class — a Fighter 3 / Rogue 2 is a level-5 character at +3, not +2. The single most common multiclass mix-up; the multiclassing guide handles the rest of that math — including a multiclass spell slot calculator.
The level-by-level table
Proficiency bonus, when you get an Ability Score Improvement (ASI), and the headline milestone at each level. Exact features vary by class — generate one to see the specifics.
Tier 1 — Local Heroes · Levels 1–4
Fragile but finding your feet. You menace goblins and bandits, and one bad fight can end you.
| Lvl | Prof. | ASI | Highlight |
|---|---|---|---|
| 1 | +2 | — | Class features begin; full casters cast 1st-level spells. |
| 2 | +2 | — | A second class feature for most classes. |
| 3 | +2 | — | Subclass comes online (level 3 for all classes in the 2024 rules); full casters reach 2nd-level spells. |
| 4 | +2 | ASI | First Ability Score Improvement (or a feat). |
Tier 2 — Heroes of the Realm · Levels 5–10
The famous "sweet spot" — powerful enough to feel heroic, not yet so high the math goes silly.
| Lvl | Prof. | ASI | Highlight |
|---|---|---|---|
| 5 | +3 | — | The biggest jump in the game: martials gain Extra Attack, full casters gain 3rd-level spells (Fireball, Counterspell), and proficiency rises to +3. |
| 6 | +3 | — | A subclass or class feature; Fighters get a bonus ASI here. |
| 7 | +3 | — | Full casters reach 4th-level spells. |
| 8 | +3 | ASI | Ability Score Improvement. |
| 9 | +4 | — | Full casters reach 5th-level spells. |
| 10 | +4 | — | A subclass feature; Rogues get a bonus ASI here. |
Tier 3 — Masters of the Realm · Levels 11–16
Genuinely powerful. High-level spells and signature class features reshape encounters.
| Lvl | Prof. | ASI | Highlight |
|---|---|---|---|
| 11 | +4 | — | Full casters reach 6th-level spells; Fighters gain a third attack. |
| 12 | +4 | ASI | Ability Score Improvement. |
| 13 | +5 | — | Full casters reach 7th-level spells. |
| 14 | +5 | — | A subclass feature; Fighters get a bonus ASI here. |
| 15 | +5 | — | Full casters reach 8th-level spells. |
| 16 | +5 | ASI | Ability Score Improvement. |
Tier 4 — Masters of the World · Levels 17–20
Legendary. World-shaking magic and class capstones. Rarely played, always memorable.
| Lvl | Prof. | ASI | Highlight |
|---|---|---|---|
| 17 | +6 | — | Full casters reach 9th-level spells (Wish, Meteor Swarm). |
| 18 | +6 | — | A major class feature for most classes. |
| 19 | +6 | ASI | Final standard Ability Score Improvement. |
| 20 | +6 | — | Class capstone — your character’s defining high-level ability. |
The power spikes that matter
Not every level lands the same. Level 5 is the legendary one — martials swing twice (Extra Attack), full casters unlock Fireball-tier 3rd-level magic, and proficiency hits +3. The community calls 5–10 the sweet spot: powerful enough to feel heroic, not yet so high the math gets silly. Level 11 adds 6th-level spells and a Fighter’s third swing; 17 opens 9th-level magic like Wish; 20 is your capstone. Running a one-shot? 5 and 11 are the crowd-pleasers.
Roll for HP, or take the average?
Rolling your Hit Die is a thrill — and a trap. Roll a 1 and your character is made of glass for the entire level. Average is the safe, smart default: a fixed, respectable number every time, no heartbreak. Plenty of generous DMs split the difference with a house rule — roll, but if you roll under the average, take the average instead. Upside with no gut-punch.
ASI or feat?
Every few levels (4 / 8 / 12 / 16 / 19) you hit the same fork: raise your stats, or take a feat. The choice that’s right most of the time is simple — drive your main attack or spellcasting stat to 20 first. A higher main stat lifts your accuracy, your damage, and your spell save DC all at once. Take a feat instead only when it’s genuinely build-defining (a ranged build that lives on its signature shot; a caster who must hold concentration through a beating).
One scope note: feats are an optional rule, and most of the famous ones live in the full books, not the SRD this tool is built on — so the generator leans on the always-correct ASI. The big names you’ll see on forums (Great Weapon Master, Sharpshooter, Sentinel, War Caster, Lucky) are excellent, and outside our SRD scope; grab them from the official rules if your DM is using feats.
Swapping spells when you level
Tired of that spell you never actually cast? Whether you can trade it depends on how your class learns magic:
- Known casters (Bard, Sorcerer, Warlock, Ranger) — when you gain a level, you may swap one known spell for another from your list. One per level, so choose well.
- Prepared casters (Cleric, Druid, Paladin, Wizard) — you don’t even wait for a level-up. Re-prepare your whole list after any long rest. (Wizards still cast from their spellbook, so you can only prepare what you’ve scribed into it.)
What level should you start at?
Most campaigns open at level 1 (you grow up together, every scar earned) or level 3 (your subclass is online, so the character already feels like itself). One-shots love level 5 for the spike. And if a character dies mid-campaign? The table wisdom is near-unanimous: the replacement joins at the party’s level, not level 1 — nobody has fun being the fragile tagalong. Whatever level you need, the character creator builds a complete, rules-accurate sheet at any level 1–20 — stats, spells, gear, a backstory, and a portrait — from one sentence.

Frequently asked questions
How do I level up my character in D&D 5e?
Six steps: pick your class (or multiclass), add a Hit Die of HP, take your new class features, update your spells, bump your proficiency bonus at 5/9/13/17, and take an ASI or feat at 4/8/12/16/19. Do it between sessions so it doesn't stall the game.
What do you get when you level up?
More hit points, new class features, and at set levels a higher proficiency bonus and ability score increases. Spellcasters also unlock higher-level spells as they climb.
When do you get Ability Score Improvements?
At levels 4, 8, 12, 16, and 19 for most classes. Fighters get extra ones at 6 and 14, and Rogues get an extra at 10. Each ASI is +2 to one ability or +1 to two — or a feat.
Should I take an Ability Score Improvement or a feat?
Default to pushing your main attack or spellcasting stat to 20 first — it raises your accuracy, your damage, and your spell save DC all at once. Take a feat instead only when it's genuinely build-defining. (Feat selection isn't in the generator yet, so it takes the always-correct ASI in its place — the optimal stat bump every time.)
Should I roll for hit points or take the average?
Average is the safer, smarter pick — a fixed, respectable number with no risk of a low roll that leaves you fragile for the whole level. If you love rolling, a common house rule is 'roll, but never below the average.'
What is the biggest power spike?
Level 5. Martials gain Extra Attack, full casters gain 3rd-level spells like Fireball, and proficiency rises to +3. Levels 5–10 are the campaign sweet spot.
Should I level up in the middle of a session?
No — level up between sessions. It means reading rules, making choices, and a little math; doing it mid-game halts the momentum. Most DMs warn you a session ahead so your sheet is ready.
Should the whole party be the same level?
5e is balanced around a same-level party. A lower-level character feels fragile and useless in a fight, which breeds resentment — so keep everyone synced.
If my character dies, do I start over at level 1?
No. The near-universal table convention is that a replacement joins at the party's current level — starting at 1 against level-6 threats is miserable and mathematically hopeless.
Does proficiency bonus scale with class level or total level?
Total character level. A Fighter 3 / Rogue 2 is a level-5 character with a +3 bonus, not +2 — a classic multiclass mix-up. The multiclassing guide covers the rest of that math.
Can I swap a spell when I level up?
Known casters (Bard, Sorcerer, Warlock, Ranger) may swap one known spell for another when they gain a level. Prepared casters (Cleric, Druid, Paladin, Wizard) don't even wait — they re-prepare their whole list after any long rest.
What level should I start a character at?
Most tables start at 1 or 3 (level 3 because your subclass is online and the character feels complete). One-shots love 5 for the power spike. You can generate a character at any level 1–20 here.
Does this cover the 2024 rules?
Yes. The core leveling structure — proficiency bonus, ASIs at 4/8/12/16/19, the four tiers, spell progression — is the same in the 2014 and 2024 (5.5e) rules. The generator supports both editions.
Is it free?
Yes — free, no login.
