Start with four heroes who can survive the front line, attack from the back and recover between fights. Underkeep rewards a party whose equipment and actions work together more than four isolated character ideas.
Prepare before entering
Open the settings and choose readable text, comfortable movement animations and a suitable difficulty. The developer has confirmed adjustable difficulty; you do not need to restart merely to make combat more manageable. Read each hero’s race traits as well as their class description before accepting the group.
Choose a front-line weapon user, another hero who can contribute up close, a ranged or magical attacker and a recovery option. These are useful planning roles, not mandatory class slots. Check that every character can actually use the equipment and skills you intend to give them.
A safe first exploration loop
- Examine the visible area and collect reachable supplies.
- Open the map and identify the route back before entering a new passage.
- Recover health and casting resources when no enemies are nearby and food is available.
- Save before a new encounter, an uncertain choice or a puzzle you can rearrange.
- Position the party before attacking. Work through the round, then assess what changed.
- Mark unfinished doors, obstacles and suspicious walls so you can return with the right tool.
This is a repeatable decision process, not a room-by-room route. The dungeon is handcrafted; this guide does not invent a mandatory opening sequence or tell you to spend quest items at an unverified location.
Know which version you are playing
The free demo is a separate application. Old demonstration routes and a preset party are not proof of the full game’s party creator or quest outcomes. Full-game guides here use the launch-period sources, with demo-specific advice labelled separately.
If progress slows down
Review your formation, resource levels and map notes before creating a new party. A reach restriction, missing tool or already-spent action can explain a problem without a bug. For a persistent blocker, record the location and installed build and consult the current fixes.
