L
GREETING
Welcome back, Mage! I've been watching your progress — you're struggling a bit with formal register. Let me guide you through this merchant encounter.
📜
combien (French) — from Old French com bien, meaning "how much good/well." The word bien traces to Latin bene. Knowing Latin roots unlocks dozens of Romance language words instantly.
🏛️
In French markets, it's considered polite to greet the merchant with "Bonjour" before asking any question. Skipping the greeting can come across as rude — cultural fluency matters as much as vocabulary!
⚗️
"Ça coûte combien?" uses the verb coûter (to cost). Notice subject-verb inversion isn't required in casual speech — "combien ça coûte" works equally well in everyday conversation.
🧠
Memory hook: COMBIEN = COMBINE + END — imagine combining coins at the END of a transaction. You're combining how many coins you need. Visualization: a glowing coin chest with a "?" above it.

Frequently Asked

Your Questions,
Answered

Which languages can I learn on Runebound?

Runebound currently offers 12+ languages including Spanish, French, Japanese, Mandarin, German, Italian, Portuguese, Arabic, Korean, Russian, Dutch, and Swedish. New languages are added quarterly — Legend subscribers get early access.

Do I need to download anything?

Nothing. Runebound is fully browser-native — open it in Chrome, Firefox, Safari, or Edge and you're ready to quest. No app store, no installer. Your progress syncs automatically across devices.

Is Runebound suitable for complete beginners?

Absolutely. When you start, you choose your proficiency level (Novice, Apprentice, or Adept). The Whispering Forest realm is designed for total beginners and eases you into vocabulary and grammar through context-rich NPC conversations before introducing anything complex.

How is Runebound different from Duolingo?

Duolingo uses a mobile-game loop with cartoon mascots and short drills — excellent for habit formation but thin on depth. Runebound is built for adult learners who want narrative immersion: full NPC quest lines, an unlockable overworld, and an RPG reward system. You learn by completing actual story objectives, not by tapping matching tiles.

Can I cancel my Legend subscription anytime?

Yes, with no questions and no penalty. Cancel from your profile settings in under a minute. You keep full Legend access until your billing period ends, then drop to free explorer mode — your progress, spellbook, and realm history are preserved.

When does the 7-day free trial end and billing start?

Your trial begins the moment you create your account. If you upgrade before the 7 days end, billing starts immediately on that date. If you don't upgrade, your account automatically moves to free explorer mode with access to the first realm only — no charge, no card needed for the trial.
