I watched my party crumble in the final hallway, one bad class swap away from a wipe. You feel that quiet, sudden regret when a single choice turns every plan into rubble. The wrong pick is a powder keg.
I’ve run every class through dozens of Steam sessions, read Discord threads, and watched Twitch streamers test odd synergies so you don’t have to guess in the heat of a run. I’ll tell you what works, why it works, and when a risky option is worth keeping. Read fast—these decisions decide runs.
Complete Underkeep class tier list
At 2 a.m. I refreshed the Underkeep subreddit and saw the same debate: which class actually changes a run? Below is a concise tier breakdown I use when I’m planning a team or solo route.
- S-tier: Core carries. High impact, flexible roles, and forgiving builds.
- A-tier: Strong when paired right. They need allies or items to shine.
- B-tier: Fun and powerful in the right hands, but build-dependent and fragile.
S-tier
On a stream I noticed successful parties almost always featured at least one of these classes. They tilt fights in your favor and reduce guesswork.
- Warrior: The Warrior is a Swiss Army knife. You can craft tanks, off-tanks, or damage dealers and still be useful. Builds are forgiving and let you swap roles mid-run.
- Wizard: High single-target and AoE damage once elemental stacks are set. Low HP, yes—but barrier tools and crowd disruption make the Wizard a premier DPS when you plan fights around its spells.
- Paladin: Tank with heals and strong resistance versus Demons and Undead. If you need a frontline that keeps the team alive and controls aggro, the Paladin is the safest bet.
What is the best class in Underkeep?
The simple answer: context matters, but the Warrior is the safest universal pick for most players. If you aim to carry raw damage and can babysit positioning, the Wizard becomes the best single-character DPS. I recommend checking Steam guides and IGN write-ups if you want build templates; many creators post polished Wizard rotations there.
A-tier
In beta sessions and public matches I found these classes swing big when paired correctly; otherwise they stall progress.
- Blood Mage: Damage-wise, it can rival S-tier output—but the cost is complex resource management and surgical play. Best with a Ranger partner who can mark targets and keep pressure while you convert life to damage.
- Ranger: Reliable precision and target marking make it excellent for teams that need focused takedowns. Its damage is steady, not flashy, which is exactly what many parties need.
- Voidcaller: The premium support: heals, barriers, and debuffs. It’s the glue class for sticky fights, though in my testing a Paladin often outperforms it in pure survivability scenarios.
Which class is best for support in Underkeep?
Voidcaller is the answer if you need utility and team healing; Paladin if you want survivability plus off-heals. I’ve seen Voidcaller builds featured on Reddit and discussed in Discord strategy channels; if you prefer passive sustain and debuffs, start there.
B-tier
In one speedrun I watched a Thief carry for two floors and then fall apart on a single boss mechanic. That’s the feeling B-tier gives: thrilling, fragile, and conditional.
- Thief: High crit and evasion can feel exhilarating, but the class demands patient leveling and perfect item choices. If you enjoy high-skill play and planning your crit windows, it’s rewarding; otherwise it stalls runs.
Is Blood Mage worth it in Underkeep?
Yes, if you master its resource tempo. The payoff is massive DPS, but mistakes cost you heavily. If you’re building a team, pair it with a Ranger and a Paladin or Voidcaller on standby.
I reference Steam community builds, Twitch runs, and Reddit test logs when I iterate my own guides; these sources will save you hours compared with trial-and-error. There’s even a small $14.99 (€15) mini-pack on Steam that adds cosmetic variety and makes testing feel less grindy.
Pick the class that matches how you like to play: do you want control, damage, or chaos? Which choice will you trust with your next run?
