A guide for multiclass builders: what to have ready, the steps to preview feat and spell choices by level, and what to check before you choose a tool.

## What you need before you start

Gather the basics for any browser tool. You need a current web browser and a stable internet connection. Have the rulebooks your table allows handy, so you can verify any feat or spell that appears. Write down the classes you intend to combine and the target overall level of the character. Keep a short list of questions ready, such as whether the tool shows feats at each level, filters spells by class and level, and works entirely in the browser.

## Step by step

These numbered steps work with any tool that shows choices level by level.

1. **Plan your class order.** List the sequence of class levels you want, for example Fighter levels one through three then Wizard levels one through five. The order determines when feats and spell slots appear.
2. **Open the builder at level one.** Enter the first class, background, species, and ability scores. Do not jump ahead; the goal is to watch each change.
3. **Record each feat as it appears.** When the tool displays a feat choice, note the level and the options available.
4. **Track spell slots at every level.** Multiclass spell slots have their own table, so write down the numbers the builder shows and compare them to the rules.
5. **Filter the spell list.** Use the tool's search to show only spells of the current class and level. Write down which spells are available at that step.
6. **Add the second class at the planned level.** When you reach the level where the new class begins, input it and observe any changes to feats, slots, or features.
7. **Check any item or feature math.** If the tool updates numbers when you add a magic item, verify the note explains the change.
8. **Save the build and repeat with a different order.** Keeping notes lets you compare how swapping class order shifts the timing of feats and spells.
9. **Choose the order that gives the desired options.** After comparing at least two sequences, settle on the one that matches your desired feat and spell progression.

## Tools that can do it

The facts available cover one tool in detail, so the list is concise.

**Tavern Bag.** It is made by Lunar Werx, the team that publishes this site. [^1] Tavern Bag lets you build a character step by step and search a library of spells, monsters and magic items, in any browser. [^1] The character builder covers class, background, species, ability scores, subclass, feats and gear. [^1] You can search the whole library at once or filter it by book, level and class. [^1] The library, which opens after a free sign-in, has 1,817 spells [^1], 3,144 monsters [^1], 2,861 magic items [^1] and 175 rules pages [^1] from 18 openly licensed books. [^1] When you put on a magic item, the numbers change, with a note saying why. [^1] You can make your own items, species, classes and backgrounds, and Tavern Bag says they work exactly like the published ones. [^1] Tavern Bag says it works in any browser, on a phone or a laptop, and your characters follow your sign-in. [^1] The free plan keeps 3 characters [^1], with no trial and no card required. [^1] Tavern Bag Unlimited [^1] at $3.99 a month [^1] lets you keep as many characters as you like. [^1]

**Other character builders.** Any other tool can be evaluated with the same checklist: step by step building, spell filtering by class and level, and a clear note on what the free offer includes. Check each point on the tool's own page before deciding.

## Common mistakes to avoid

**Skipping to the final level.** Building from level one lets you see when feats and spell slots appear, which is essential for multiclass planning.

**Overlooking multiclass spell slot rules.** The slot table differs from single class tables; always compare the builder's numbers to the official rules.

**Ignoring class order.** Changing which class you take first can move feats and spells to different levels; try at least two orders.

**Using a tool that hides intermediate steps.** If a builder only shows the finished character, it does not help you plan level by level choices.

**Assuming the spell list matches your allowed books.** Verify which sourcebooks the tool includes and ensure they align with your table's allowed material.
