Frequently Asked Questions About the D&D Spell Generator

What does this D&D spell generator produce?⌄

Every spell includes spell level, school, casting time, range, components, duration, and a balanced effect description. Outputs are remix-ready so you can adapt them to any campaign setting or homebrew system.

What is spell level in D&D?⌄

Spell level is the power tier of a spell (0-9), determining which spell slot you use to cast it. Cantrips are level 0; Wish is level 9.

How do I balance a custom spell in D&D 5e?⌄

Compare damage and utility to official spells of the same level. Use the DMG spell design guidelines (p. 283-284) and playtest with your group. WorldSmith generates spells using 5e damage benchmarks as a starting point.

What makes a homebrew spell overpowered?⌄

Damage exceeding official benchmarks (e.g., 10d6 for a 3rd-level spell), no-save effects, or utility that trivializes encounters (e.g., free teleportation). Always compare to existing spells of the same level.

How does spell damage work in 5e?⌄

Roll the dice listed in the spell description. Add your spellcasting modifier only if the spell explicitly says so (most damage spells do not).

How do I calculate spell save DC?⌄

8 + your proficiency bonus + your spellcasting ability modifier (INT for wizards, WIS for clerics, CHA for sorcerers).

Can you create custom spells in D&D?⌄

Yes — the DMG includes spell design guidelines (p. 283-284). Many DMs allow homebrew spells with approval. Use a spell generator for instant, balanced ideas.

What does a random spell generator do?⌄

It picks spells from the 5e SRD for quick NPC spellbooks, loot drops, or inspiration. Filter by level, school, or class.

How do I generate a wizard spellbook?⌄

Use a spellbook generator to pick spells by level and school, then tailor the list to your NPC backstory. A 5th-level wizard knows roughly 14 spells (2 per level + INT modifier).

Is the spell generator free to try?⌄

Yes. WorldSmith offers a free 7-day trial with full access to every generator, including spells. After the trial, plans start at $5 per month. Remixing and editing shared spell creations is always free with an account.
