Underkeep Turn Based Combat Guide: How Rows, Actions, and Mana Shape Every Fight

Underkeep turn based combat is the reason this old-school dungeon crawler feels more like a tense conversation than a reflex test: each of your four adventurers acts, then the monsters answer. Rake in Grass released the game on November 5, 2026, and its fights are built on grid movement, front-and-back rows, and exactly one action per character per turn. If you are deciding whether the Underkeep turn based combat system has enough tactical depth to hold you for a full campaign, here is how the loop actually plays, how to prepare between fights, and where the real pressure comes from.

How Underkeep Turn Based Combat Actually Works

The core rhythm is simple to describe and surprisingly easy to misjudge. Your party of four takes its actions one character at a time, then the enemy side responds. Repeat. That structure is a deliberate nod to the classics the developers name as influences — Dungeon Master, Lands of Lore, Eye of the Beholder, Wizardry, and Ishar — rather than to modern squad tactics games.

The important nuance is that there is no separate battle screen. In the official Steam discussion thread where the developers answer questions about the combat model, one clarifies that approaching enemies effectively put you into a fight, while another adds that the level itself keeps advancing on its own turn-based schedule. Levers can still be pulled, doors still open, pits can still swallow a careless step, and a second monster can walk up behind you mid-fight. Traps, as the developers joke, do not wait their turn.

That last point about the grid matters. The developers explicitly chose not to bolt on a separate tactical grid battle mode, arguing that a second combat layer would slow the pace of a game already full of encounters. So if you arrive expecting XCOM-style flanking puzzles, adjust your expectations: the tactics here live in party composition, row placement, skill timing, and resource management instead.

Rows, Positioning, and the One-Action Rule

Your four heroes are split across two rows. Tougher, heavily armored characters belong in front, where they soak up attention, while casters and support types sit behind them. Since every character gets a single action per turn, the question is never "how many buttons can I press" but "which one action is worth the most right now."

A few details shape that decision more than they first appear to:

• Potions and consumables are free. Drinking a healing potion does not spend your action, which makes potion-chugging a legitimate tactic in a bad turn rather than a wasted one.
• Skipping is a real move. If enemies are far away and only your ranged characters can reach them, skipping the front line preserves tempo instead of wasting attacks.
• Hotkeys speed things up. Number keys 1–4 trigger auto-attacks for each party member, which keeps routine encounters from dragging.
• Physical attacks can miss. Armor reduces them further, so front-row damage is never guaranteed.

Physical vs. Magical Attacks and the Resource Game

Underkeep splits damage into two broad flavors, and they behave differently enough that you should plan around both.

Because mana does not regenerate on its own while you are exploring, every spell is a withdrawal from a limited account. Player experience from early coverage of the game stresses the same point: you are expected to carry consumables, keep food on hand, and think about a fight before it starts. The Steam page frames it bluntly — turn-based battles reward planning, space control, and wise stamina and mana management, while carelessness gets punished.

That design choice is why the preparation layer of Underkeep turn based combat matters as much as the turns themselves. Vendors, equipment upgrades, and potion crafting all feed directly back into how long your party can keep casting before it has to fall back on steel.

Building a Party Around the Combat

Before your first fight, you assemble four adventurers. One before-you-buy overview reports six playable races and seven classes with roughly 70 skills to experiment with, and notes that party composition makes a meaningful difference in how encounters play out. You can stack melee protection in front of spellcasters, or build something stranger.

Progression reinforces this. Characters earn one skill point per level, split between active skills that define a playstyle and passive skills that quietly raise your floor. Base attributes do not shift as you level, so itemization and skill investment do the heavy lifting; equipment can push elemental damage, survivability, or the reliability of status effects. The Steam store page summarizes the philosophy neatly: a good team deepens your strategy, and a bad one seals your grave.

If you want to skip the spreadsheet phase, one reviewer recommends the quick-start party for newcomers, reporting that it carried them through a full normal-difficulty run without feeling like a compromise. That is player experience rather than a guarantee, but it is a reasonable on-ramp while you learn the Underkeep turn based combat rhythm.

Practical Tips for Your First Fights

• Save before you commit. Autosaves trigger when you enter a map subsection, but manual saves let you rewind a bad fight or a bad dialogue choice.
• Read your tooltips. Item descriptions in this game hide secondary uses and useful context that the tutorial will not spell out for you.
• Keep the back row ranged. A caster standing in the front is an action spent healing instead of casting.
• Treat potions as free tempo. Since consumables do not consume your turn, saving them "for later" is usually a mistake.
• Do not plan on grinding. Enemies generally do not respawn indefinitely, and the adventure is built as a finite, handcrafted campaign rather than a farming loop.
• Expect a shorter campaign than a modern CRPG. The publisher's press release pitches 15–20 hours of exploration and hidden secrets, though at least one player reported a longer 25–40 hour run. Your pace will vary with how thoroughly you poke at walls.

For reference on scope and reception: as of November 6, 2026, the official Underkeep Steam store page recorded a Very Positive rating, with 94% of 319 user reviews positive. The same snapshot listed an introductory 15% discount — $19.50 down from $22.95 — with the offer noted to end November 19. The game supports controllers alongside mouse and keyboard, and Steam Deck compatibility is marked Playable.

FAQ

Is Underkeep turn based combat hard to learn?

No. Each character takes one action per turn, then enemies respond, so the basic loop clicks within a fight or two. The depth arrives later through skill investment, row placement, and mana discipline rather than through complicated inputs.

Can I still move around during a fight?

Yes. Combat happens on the same grid you explore on, and the surrounding level keeps advancing on its own turn-based schedule while you fight. You can pull levers, open doors, and even fall into pits mid-battle, and additional monsters may close in from behind.

Do enemies respawn in Underkeep?

Generally not. Community reports describe the game as a finite adventure built around handcrafted encounters rather than endless respawns, so experience and loot are limited — which rewards thorough exploration over farming.

What makes Underkeep turn based combat different from other RPGs?

It keeps the streamlined, one-action-per-hero structure of '90s dungeon crawlers rather than adding a separate tactical grid battle mode. The pressure comes from positioning, resource scarcity, and a world that refuses to pause politely while you fight.
