Underkeep: Skills for All 7 Classes

Underkeep
All Underkeep guides

Every Underkeep class has its own skill set, and not all of them use the same resource. Warriors, Thieves, and Rangers pay in Stamina, Paladins spend Zeal, Wizards and Voidcallers use Mana, and Blood Mages pay with their own HP plus a bone.

Skill values change at each level from 1 to 5, and many skills also need a certain hero level or weapon before they are useful. Some only shine in the right setup, like Zeal finishers on a Paladin or the bleed and poison combo on a Thief.

How Skills Work for All 7 Classes

  • You get 1 skill point per level. A skill can hold up to 5 points.
  • Active skills sit in the slot next to the basic attack. Right-click that slot to switch between them. Passive skills are always on.
  • Many skills only work with a certain weapon type, so check the tooltip before you spend a point.
  • Every skill has a minimum hero level before it can take a point. In the tables, this is shown as Unlock.
  • The big damage skills all unlock at level 6: Fireball, Ice Tower, Storm Chain, Execution Shot, Shadow Lunge, Bloodfall, and Judgment.

Skill Picks by Class

Warrior

  • Choose skills that fit the weapon you carry: Flurry Thrust for swords, Skull Rattle for maces (it stuns), Slice and Dice for axes (it ignores armor), Cleave for two-handers (it hits two enemies), Riposte for one-handers, and Shield Bash for shields (it stuns and adds passive armor).
  • Champion’s Grip does not use an action. It gives more damage and stun immunity, so cast it at the start of hard fights.
  • Provoking Shout draws enemy attacks to the Warrior. Use it when another front-row hero is hurt.
  • Battle Roar buffs the whole party.
  • The Flow of Life is a passive that adds max HP and elemental resistance. It is a good place for spare points.

Paladin

  • Each basic attack that lands builds 1 Zeal, up to a maximum of 5. The Zeal finishers (Flame of Conviction, Judgment, and Stun Undead) use up all of it.
  • Righteous Strike does not use an action. It makes your next basic attack stronger and adds 1 extra Zeal. Cast it almost every round while you build Zeal.
  • Once you have 4 or 5 Zeal, spend it on Judgment, which hits Undead and Demons very hard, or on Lay on Hands to heal.
  • Divine Guard adds armor each time you spend Zeal, while Zealous Resolve adds damage for each Zeal you keep. These two passives reward opposite habits, so pick one rhythm and build around it.
  • Sacred Bulwark converts Wisdom into Armor, which gives the Paladin’s +1 WIS bonus a real use.

Thief

  • The Thief relies on evasion, which caps at 60%. Evasive Roll does not use an action and raises that cap.
  • Nightshade Mastery adds a random Poison, Bleed, Blind, or Burn to hits. Backstab the Weak then gains crit chance for each negative effect on the target, and Shadow Lunge deals more damage to bleeding or poisoned enemies. This combo is the core of the build.
  • Smoke Bomb blinds up to two enemies (-50% accuracy). It works very well against enemies that hit hard.
  • Mark the Dead is not only a Blood Mage skill. The Thief unlocks it at level 3, and the marked enemy takes +20% to +40% damage from the whole party.

Ranger

  • After Hunter’s Prey unlocks at level 5, open fights by using it on the most dangerous enemy. It only works on close enemies. Then have the whole party attack that target.
  • Execution Shot deals extra damage to targets marked by Hunter’s Prey or by Mark the Dead from a Thief or Blood Mage.
  • Skirmisher’s Step does not use an action. It gives evasion and makes the next attack stronger.
  • Runebound Arrows is a passive that adds random elemental damage to every shot.

Wizard

  • Early on, take Fire Spark (burn) or Ice Shard (freeze, which makes the enemy skip its turn).
  • For groups of enemies, use Static Shock, Fireball, Storm Chain, and Ice Tower.
  • Arcane Lock paralyzes an enemy, but a paralyzed enemy can still attack. It stops movement, not damage.
  • Dragon Arcana and Feel the Flow are the key passives.
  • Invisibility hides the whole party until you act, which helps you sneak past threats.

Voidcaller

  • Void Mend heals, and at levels 2, 3, 4, and 5 it also removes Bleed, Burn, Poison, and Stun in that order. That makes it the best all-round cure in the game, so put points in it.
  • Void Lance ignores enemy defenses, so aim it at armored enemies.
  • Only one aura can be active at a time, and you can change it when you level up. Raising one aura raises all of them. Aura of the Void, a party barrier that renews itself, is the safe default.

Blood Mage

  • Every spell costs 1 bone and some HP. With no bones, it costs more HP instead, so pick up every bone and skull you see.
  • Leechcraft heals you for 10% to 50% of the blood damage you deal. Take it as soon as it unlocks at level 5 to make up for the HP cost.
  • Blood Lance and Bloodfall are 30% weaker against Undead, so let the Paladin deal with crypts.
  • Exsanguinate boosts a bleed that is already on the target. Combine it with Bloodfall or with the Thief.
