Use Options > Controls as the source of truth for your current bindings. The launch-period player guide reports useful defaults, but saved settings and input devices can differ.
Common default actions
| Action | Reported default |
|---|---|
| Grid movement, strafing and turning | W, A, S, D, Q, E or arrow keys |
| Map | M |
| Change target | Tab |
| Pick up nearby items together | Y |
| Pick up a single item | Right-click or drag to inventory |
| Change the active skill | Right-click its slot beside the basic attack |
| End the round | Hourglass control |
This is a compact reference to the current player guide, not a verified controller button map.
Configure for your party
- Open the Controls settings.
- Locate the action you actually need rather than trying unrelated keys.
- Check whether a custom binding replaced the reported default.
- Consider assigning comfortable per-hero Attack and Use Skill keys.
- Confirm the binding with a safe action before entering a difficult encounter.
The guide reports that panels, quick save/load, rest and round skipping can also be rebound. Use the game’s menu to inspect conflicts instead of assuming two actions can share a key safely.
Movement versus turning
In a grid crawler, changing facing and moving sideways are different commands. Test them in a safe space so an intended sidestep does not turn the party toward a threat.
When an input seems broken
Check whether combat movement is locked, a skill is on cooldown or a requirement is missing before diagnosing the keyboard or controller. A command can be received correctly while the game state prevents its action.
