How to unlock Frosthaven classes
Updated
Board game: unlock a class when a campaign reward instructs you to open its box. Do not assume personal quest completion and retirement are the direct route to every class.
The path that is actually documented
Personal quests establish retirement goals and can unlock scenario chains. That does not prove the retired character's reward is a new class. Follow each actual reward instruction and distinguish building envelopes from class boxes.
For a quest that says to follow a scenario to its conclusion, wait for the explicit gold Scenario Rewards completion instruction. Collection quests instead use their own conditions; those must still be met when retirement is checked.
- Keep a record of unlocked and completed scenarios using the campaign tracker.
- Open only the specific box or envelope named by a reward.
- Do not replay a completed scenario to claim a different Scenario Reward.
- Keep retirement, building unlocks and class unlocks as separate campaign records.
Locked-class opening conditions: spoilers
The six starting classes are available at campaign setup. These rows concern the remaining class boxes. Follow the actual reward section after a successful conclusion; simply opening a scenario does not grant its reward.
For building routes, first unlock the building envelope, meet its requirements and pay the build or upgrade costs. Reaching prosperity alone does not open the class. These are board-game records, not a verified promise about every digital client save.
The snapshot's rewards array is indexed by target level: index 0 is level 1, index 1 is level 2. Compare building progression, personal quests and campaign progress.
| Class / code | Recorded opening condition | Reward evidence |
|---|---|---|
| Frozen Fist / Fist | Scenario 4: Snowdancer dies; alternatively scenario 56. Scenario 55 offers a Fist/Snowflake choice. | Sections 15.2A/B; scenarios 55 and 56 |
| Snowdancer / Snowflake | Scenario 4: Frozen Fist dies; alternatively scenario 57. Scenario 55 offers the same choice. | Sections 22.1A/B; scenarios 55 and 57 |
| Crashing Tide / Coral | At scenario 14 choose Coral or Kelp. Scenario 60 repeats the choice for a still-locked candidate. | Scenarios 14 and 60: chooseUnlockCharacter |
| Deepwraith / Kelp | The other candidate in the scenario 14 / 60 choice. One choice reward does not grant both boxes. | Scenarios 14 and 60: chooseUnlockCharacter |
| HIVE / Prism | Complete scenario 58 Orphan's Core or 59 Automaton Uprising. | Scenarios 58 / 59: unlockCharacter=prism |
| Shattersong / Shards | Complete scenario 61 Life and Death. Reaching that scenario is separate from its completion reward. | Scenario 61: unlockCharacter=shards |
| Pyroclast / Meteor | Upgrade building 05 Mining Camp to level 2 and resolve section 49.2. | Building 05 rewards[1] -> section 49.2 |
| Trapper / Trap | Build building 12 Hunting Lodge at level 1 and resolve section 172.3; level 2 is not required by this reward. | Building 12 rewards[0] -> section 172.3 |
| Pain Conduit / Shackles | Upgrade building 44 Enhancer to level 2 and resolve section 157.2. | Building 44 rewards[1] -> section 157.2 |
| Infuser / Astral | Upgrade building 83 Library to level 2 and resolve section 116.3. | Building 83 rewards[1] -> section 116.3 |
| Metal Mosaic / Drill | Open the puzzle book, reach pages 4–5 and solve the Ancient Technology side puzzle. Within Frosthaven, scenario 27 or 41 supplies the clue. Follow the solved reward's box-opening instruction. | Original community guide, cross-checked against the relevant Section Book reward; no decoded answer reproduced |
Questions
How do I unlock the Drill?
In the board game, progress to the Ancient Technology side puzzle on puzzle-book pages 4–5. Scenario 27 or 41 supplies the Frosthaven clue. Solve that side puzzle and follow its reward instruction to open the class box; neither retirement alone nor completing the entire puzzle book is required by this route.
Did I permanently miss a class?
FAQ section 7.1 says classes still unlock across the campaign even if you cannot replay a scenario for the other reward.
