How to Level Up in Solo D&D

Leveling up is a milestone in any D&D campaign. Your character gets stronger, unlocks new abilities, and feels the progression of their arc.

In solo AI D&D, leveling up works the same as group play but you make every decision yourself.

When You Level Up

Two common systems:

XP-Based Leveling

You earn experience points (XP) from encounters. At certain thresholds, you level up.

Milestone Leveling

You level up at specific story beats (end of chapter, defeating a boss, etc.).

The Endlessness supports both. Most campaigns use milestone by default.

What Changes at Level Up

1. HP Increase. Roll your hit die + Con mod, OR take the average (+Con mod).
2. Class Features. You gain the features listed for your new level.
3. Proficiency Bonus. Increases at levels 5, 9, 13, 17.
4. Spell Slots. Gain new slots based on class progression.
5. Spells Known / Prepared. Known casters learn new spells. Prepared casters can prep more.
6. Subclass features at specific levels (usually 3, 6, 10, 14, 18).
7. Ability Score Improvements at levels 4, 8, 12, 16, 19 (Fighter gets extra at 6 and 14).

Leveling Up in The Endlessness

The AI prompts you when you level up:

1. Notifies you that you can level up.
2. Walks you through HP, feature, and spell choices.
3. Applies your choices to your character.

You don't need to do any manual tracking. The system handles the math.

HP Roll vs. Average

When you level up, you can:

• Roll your hit die (e.g., d10 for Fighter). Hope for a high number.
• Take the average (5.5 rounded up to 6 for d10).

Average is safer. Rolling is exciting but risky. Most players take the average.

Picking Features

Each class gets different features at each level. For example:

• Barbarian level 5: Fast Movement, Extra Attack.
• Wizard level 3: 2nd-level spell slots, new spells for your spellbook.
• Rogue level 5: Uncanny Dodge, 3d6 Sneak Attack.

The AI explains each feature as you level up.

Picking Spells (for Casters)

At level-up, you gain access to new spell levels or more spells known.

Factors to consider:

• What do you lack? Damage? Healing? Utility?
• What campaign needs are coming? Check the current arc.
• What synergizes with your existing spells?

See our class guides for spell recommendations.

ASIs and Feats

At ASI levels (4, 8, 12, 16, 19), you choose:

• +2 to one stat, OR
• +1 to two stats, OR
• A feat.

See our ASI vs. feat guide.

Multiclassing at Level Up

If you're multiclassing, you choose a class at level-up. Must meet ability score requirements.

See our multiclassing guide.

Tips for Leveling Up

• Take your time. Don't rush level-up decisions.
• Read your class guide. Refresh on the new features.
• Plan a few levels ahead. Know what's coming.
• Don't always pick the "optimal" choice. Pick what fits your character.
