You can change Underkeep’s difficulty during the game. The developer describes three settings that primarily alter combat difficulty, so a difficult encounter does not by itself require a fresh campaign.
Diagnose before changing
First check that all four heroes can contribute. An empty resource, a back-row melee restriction or a status effect can make a normal encounter feel much harder. A difficulty change may reduce pressure without fixing those underlying problems.
If you prefer a lower-pressure experience, use the setting that suits you. There is no requirement to preserve a higher difficulty while learning the systems.
A controlled adjustment
- Preserve a useful save before retrying the encounter.
- Open the difficulty option in the installed game’s settings.
- Read the available choice and select the level you want.
- Revisit the fight with the same broad plan so you can see what changed.
- Review formation and resource use if the problem persists.
The exact menu layout can vary. This page does not invent hidden modifiers or a numerical multiplier table.
What the announcement does not establish
“Primarily combat” is not a verified list of every affected system. Do not assume puzzle solutions, loot tables, food costs or achievement eligibility are unchanged merely from that phrase. Those questions require specific current documentation.
Keep comparisons meaningful
When asking for build help, mention the selected difficulty, game version, equipment and party. A recommendation from a player on another setting may still help, but it is not a controlled measurement of your situation.
