Read the complete race and class information for all four heroes before finalizing the party. The biggest avoidable mistake is accepting a combination whose equipment, resource costs or random traits undermine the role you wanted.
Decide the job first
Write down which two heroes are intended to contribute from the front and how the other two will attack from behind. Then choose classes and races around those jobs. A familiar fantasy label is not a substitute for checking the actual character panel.
The launch-period player guide lists six races and seven classes. Older developer posts use earlier race names and an incomplete class roster; do not treat those development lists as the final character selection screen.
Check each hero
- Read the class’s main resource and starting action.
- Inspect the race trait for equipment restrictions or damage vulnerabilities.
- Confirm the planned weapon works from the assigned row.
- Read random mutations before accepting a Raven.
- Compare the whole party’s recovery and ranged options.
- Choose names and portraits, then review all four heroes together.
For a Raven, check the trait’s effect on this particular class. An increased casting cost matters to a caster in a different way than a melee drawback. The player guide describes recreating an unwanted Raven in the Party Creator; that is a creation-stage choice, not evidence of a later mutation reroll service.
Do not assume later rebuilding
These sources do not establish a safe, universal mid-campaign race change or complete respec procedure. Make the initial decision as though its major identity choices matter, and preserve a separate early save if you want to experiment.
Demo differences
Older demo material refers to a prebuilt party and provisional names. It should not be used as a step-by-step description of the current full-game creator. This guide deliberately avoids unsupported dice-locking, perfect-roll or post-creation reset instructions.

Mechanics are reported in the original player guide; developer sources support the broader system. This is not an independent verification of every tooltip or balance value.
